The previous patch allowed device drivers to publish their default
binding between packet trap policers and packet trap groups. However,
some users might not be content with this binding and would like to
change it.
In case user space passed a packet trap policer identifier when setting
a packet trap group, invoke the appropriate device driver callback and
pass the new policer identifier.
v2:
* Check for presence of 'DEVLINK_ATTR_TRAP_POLICER_ID' in
devlink_trap_group_set() and bail if not present
* Add extack error message in case trap group was partially modified

Packet trap groups are used to aggregate logically related packet traps.
Currently, these groups allow user space to batch operations such as
setting the trap action of all member traps.
In order to prevent the CPU from being overwhelmed by too many trapped
packets, it is desirable to bind a packet trap policer to these groups.
For example, to limit all the packets that encountered an exception
during routing to 10Kpps.
Allow device drivers to bind default packet trap policers to packet trap
groups when the latter are registered with devlink.
The next patch will enable user space to change this default binding.

Register three dummy packet trap policers with devlink and implement
callbacks to change their parameters and read their counters.
This will be used later on in the series to test the devlink-trap
policer infrastructure.
v2:
* Remove check about burst size being a power of 2 and instead add a
debugfs knob to fail the operation
* Provide max/min rate/burst size when registering policers and remove
the validity checks from nsim_dev_devlink_trap_policer_set()

Devices capable of offloading the kernel's datapath and perform
functions such as bridging and routing must also be able to send (trap)
specific packets to the kernel (i.e., the CPU) for processing.
For example, a device acting as a multicast-aware bridge must be able to
trap IGMP membership reports to the kernel for processing by the bridge
module.
In most cases, the underlying device is capable of handling packet rates
that are several orders of magnitude higher compared to those that can
be handled by the CPU.
Therefore, in order to prevent the underlying device from overwhelming
the CPU, devices usually include packet trap policers that are able to
police the trapped packets to rates that can be handled by the CPU.
This patch allows capable device drivers to register their supported
packet trap policers with devlink. User space can then tune the
parameters of these policer (currently, rate and burst size) and read
from the device the number of packets that were dropped by the policer,
if supported.
Subsequent patches in the series will allow device drivers to create
default binding between these policers and packet trap groups and allow
user space to change the binding.
v2:
* Add 'strict_start_type' in devlink policy
* Have device drivers provide max/min rate/burst size for each policer.
Use them to check validity of user provided parameters

Add a separate set of PCS operations, which MAC drivers can use to
couple phylink with their associated MAC PCS layer. The PCS
operations include:
- pcs_get_state() - reads the link up/down, resolved speed, duplex
and pause from the PCS.
- pcs_config() - configures the PCS for the specified mode, PHY
interface type, and setting the advertisement.
- pcs_an_restart() - restarts 802.3 in-band negotiation with the
link partner
- pcs_link_up() - informs the PCS that link has come up, and the
parameters of the link. Link parameters are used to program the
PCS for fixed speed and non-inband modes.

Factor out mapping the tx skb to a new function rtl8169_tx_map(). This
allows to remove redundancies, and rtl8169_get_txd_opts1() has only
one user left, so it can be inlined.

The qed_chain data structure was modified in
commit 1a4a69751f4d ("qed: Chain support for external PBL") to support
receiving an external pbl (due to iWARP FW requirements).
The pages pointed to by the pbl are allocated in qed_chain_alloc
and their virtual address are stored in an virtual addresses array to
enable accessing and freeing the data. The physical addresses however
weren't stored and were accessed directly from the external-pbl
during free.
Destroy-qp flow, leads to freeing the external pbl before the chain is
freed, when the chain is freed it tries accessing the already freed
external pbl, leading to a use-after-free. Therefore we need to store
the physical addresses in additional to the virtual addresses in a
new data structure.

====================
Port and flow policers for DSA (SJA1105, Felix/Ocelot)
This series adds support for 2 types of policers:
- port policers, via tc matchall filter
- flow policers, via tc flower filter
for 2 DSA drivers:
- sja1105
- felix/ocelot
First we start with ocelot/felix. Prior to this patch, the ocelot core
library currently only supported:
- Port policers
- Flow-based dropping and trapping
But the felix wrapper could not actually use the port policers due to
missing linkage and support in the DSA core. So one of the patches
addresses exactly that limitation by adding the missing support to the
DSA core. The other patch for felix flow policers (via the VCAP IS2
engine) is actually in the ocelot library itself, since the linkage with
the ocelot flower classifier has already been done in an earlier patch
set.
Then with the newly added .port_policer_add and .port_policer_del, we
can also start supporting the L2 policers on sja1105.
Then, for full functionality of these L2 policers on sja1105, we also
implement a more limited set of flow-based policing keys for this
switch, namely for broadcast and VLAN PCP.
Series version 1 was submitted here:
https://patchwork.ozlabs.org/cover/1263353/

This patch adds complete support for manipulating the L2 Policing Tables
from this switch. There are 45 table entries, one entry per each port
and traffic class, and one dedicated entry for broadcast traffic for
each ingress port.
Policing entries are shareable, and we use this functionality to support
shared block filters.
We are modeling broadcast policers as simple tc-flower matches on
dst_mac. As for the traffic class policers, the switch only deduces the
traffic class from the VLAN PCP field, so it makes sense to model this
as a tc-flower match on vlan_prio.
How to limit broadcast traffic coming from all front-panel ports to a
cumulated total of 10 Mbit/s:
tc qdisc add dev sw0p0 ingress_block 1 clsact
tc qdisc add dev sw0p1 ingress_block 1 clsact
tc qdisc add dev sw0p2 ingress_block 1 clsact
tc qdisc add dev sw0p3 ingress_block 1 clsact
tc filter add block 1 flower skip_sw dst_mac ff:ff:ff:ff:ff:ff \
action police rate 10mbit burst 64k
How to limit traffic with VLAN PCP 0 (also includes untagged traffic) to
100 Mbit/s on port 0 only:
tc filter add dev sw0p0 ingress protocol 802.1Q flower skip_sw \
vlan_prio 0 action police rate 100mbit burst 64k
The broadcast, VLAN PCP and port policers are compatible with one
another (can be installed at the same time on a port).

The approach taken to pass the port policer methods on to drivers is
pragmatic. It is similar to the port mirroring implementation (in that
the DSA core does all of the filter block interaction and only passes
simple operations for the driver to implement) and dissimilar to how
flow-based policers are going to be implemented (where the driver has
full control over the flow_cls_offload data structure).

====================
ionic support for firmware upgrade
The Pensando Distributed Services Card can get firmware upgrades from
the off-host centralized management suite, and can be upgraded without a
host reboot or driver reload. This patchset sets up the support for fw
upgrade in the Linux driver.
When the upgrade begins, the DSC first brings the link down, then stops
the firmware. The driver will notice this and quiesce itself by stopping
the queues and releasing DMA resources, then monitoring for firmware to
start back up. When the upgrade is finished the firmware is restarted
and link is brought up, and the driver rebuilds the queues and restarts
traffic flow.
First we separate the Link state from the netdev state, then reorganize a
few things to prepare for partial tear-down of the queues. Next we fix
up the state machine so that we take the Tx and Rx queues down and back
up when we get LINK_DOWN and LINK_UP events. Lastly, we add handling of
the FW reset itself by tearing down the lif internals and rebuilding them
with the new FW setup.
v2: This changes the design from (ab)using the full .ndo_stop and
.ndo_open routines to getting a better separation between the
alloc and the init functions so that we can keep our resource
allocations as long as possible.

When the FW RESET event comes to the driver from the firmware,
or the fw_status goes to 0 (stopped) or to 0xff (no PCI
connection), then shut down the driver activity. This event
signals a FW upgrade where we need to quiesce all operations and
wait for the FW to restart. The FW will continue the update
process once it sees all the LIFs are reset. When the update
process is done it will set the fw_status back to RUNNING.
Meanwhile, the heartbeat check continues and when the fw_status
is seen as set to running we can restart the driver operations.

When the link goes down, we need to disable the queues on the
NIC in addition to stopping the netdev stack. This lets the
FW know that the driver has stopped queue activity, and then
the FW can do internal reconfiguration work, whether actually
Link related, or for other internal FW needs. To do this,
we pull out the queue enable and disable from ionic_open()
and ionic_stop() so they can be used by other routines.
To help keep things sane, we swap the queue enables so that
the rx queue and its napi are enabled before the tx queue
which rides on the rx queues napi.
We also drop the ionic_lif_quiesce() as it doesn't do anything
more than what the queue disable has already taken care of.

The PTP Hardware Clock (PHC) subsystem offers an API for configuring
programmable pins. User space sets or gets the settings using ioctls,
and drivers verify dialed settings via a callback. Drivers may also
query pin settings by calling the ptp_find_pin() method.
Although the core subsystem protects concurrent access to the pin
settings, the implementation places illogical restrictions on how
drivers may call ptp_find_pin(). When enabling an auxiliary function
via the .enable(on=1) callback, drivers may invoke the pin finding
method, but when disabling with .enable(on=0) drivers are not
permitted to do so. With the exception of the mv88e6xxx, all of the
PHC drivers do respect this restriction, but still the locking pattern
is both confusing and unnecessary.
This patch changes the locking implementation to allow PHC drivers to
freely call ptp_find_pin() from their .enable() and .verify()
callbacks.

There is a possibility that cdev is removed before CPL_ABORT_REQ_RSS
is fully processed, so it's better to save it in skb.
Added checks in handling the flow correctly, which suggests connection reset
request is sent to HW, wait for HW to respond.

The locks are taken in this order during driver registration
(uld_mutex), at: cxgb4_register_uld.part.14+0x49/0xd60 [cxgb4]
(rtnl_mutex), at: rtnetlink_rcv_msg+0x2db/0x400
(uld_mutex), at: cxgb_up+0x3a/0x7b0 [cxgb4]
(rtnl_mutex), at: chcr_add_xfrmops+0x83/0xa0 [chcr](stucked here)
To avoid this now the netdev features are updated after the
cxgb4_register_uld function is completed.
Fixes: 6dad4e8ab3ec6 ("chcr: Add support for Inline IPSec").

This issue occurs only when multiadapters are present. Hang
happens because assign_chcr_device returns u_ctx pointer of
adapter which is not yet initialized as for this adapter cxgb_up
is not been called yet.
The last_dev pointer is used to determine u_ctx pointer and it
is initialized two times in chcr_uld_add in chcr_dev_add respectively.
The fix here is don't initialize the last_dev pointer during
chcr_uld_add. Only assign to value to it when the adapter's
initialization is completed i.e in chcr_dev_add.
Fixes: fef4912b66d62 ("crypto: chelsio - Handle PCI shutdown event").

'pm_nl_ctl' was adding a trailing whitespace after having printed the
IP. But at the end, the IP element is currently always the last one.
The bash script launching 'pm_nl_ctl' had trailing whitespaces in the
expected result on purpose. But these whitespaces have been removed when
the patch has been applied upstream. To avoid trailing whitespaces in
the bash code, 'pm_nl_ctl' and expected results have now been adapted.
The MPTCP PM selftest can now pass again.
Fixes: eedbc685321b (selftests: add PM netlink functional tests)
