When we re-enable ATR we need to restore the input set for TCPv4
filters, in order for ATR to function correctly. We already do this for
the normal case of re-enabling ATR when disabling ntuple support.
However, when re-enabling ATR after the last TCPv4 filter is removed (but
when ntuple support is still active), we did not restore the TCPv4
filter input set.
This can cause problems if the TCPv4 filters from FDir had changed the
input set, as ATR will no longer behave as expected.
When clearing the ATR auto-disable flag, make sure we restore the TCPv4
input set to avoid this.

This patch overwrites number of ports for X722 devices with support
for OCP PHY mezzanine.
The old method with checking if port is disabled in the PRTGEN_CNF
register cannot be used in this case. When the OCP is removed, ports
were seen as disabled, which resulted in wrong calculation of partition
id, that caused WoL to be disabled on certain ports.

A future patch needs to expand on the logic for re-enabling ATR. Doing

When hardware has trouble with a particular filter, we delete it from
the list. Unfortunately, we did not properly update the per-filter
statistic when doing so.
Create a helper function to handle this, and properly reduce the
necessary counter so that it tracks the number of active filters
properly.

When VF requests adding of MAC filters the checking is done against number
of already present MAC filters not adding them at the same time. It makes
it possible to add a bunch of filters at once possibly exceeding
acceptable limit of I40E_VC_MAX_MAC_ADDR_PER_VF filters.
This happens because when checking vf->num_mac, we do not check how many
filters are being requested at once. Modify the check function to ensure
that it knows how many filters are being requested. This allows the
check to ensure that the total number of filters in a single request
does not cause us to go over the limit.
Additionally, move the check to within the lock to ensure that the
vf->num_mac is checked while holding the lock to maintain consistency.
We could have simply moved the call to i40e_vf_check_permission to
within the loop, but this could cause a request to be non-atomic, and
add some but not all the addresses, while reporting an error code. We
want to avoid this behavior so that users are not confused about which
filters have or have not been added.

We used to use the function i40e_vlan_rx_register as a way to hook
into the now defunct .ndo_vlan_rx_register netdev hook. This was
removed but we kept the function around because we still used it
internally to control enabling or disabling of VLAN stripping.
As pointed out in upstream review, VLAN stripping is only used in a
single location and the previous function is quite small, just inline
it into i40e_restore_vlan() rather than carrying the function
separately.

Fix for "Resource temporarily unavailable" problem when virsh is
trying to attach a device to VM. When the VF driver is loaded on
host and virsh is trying to attach it to the VM and set a MAC
address, it ends with a race condition between i40e_reset_vf and
i40e_ndo_set_vf_mac functions. The bug is fixed by adding polling
in i40e_ndo_set_vf_mac function For when the VF is in Reset mode.

As well as 'auto' and the forced 'off', 'rs' and 'baser' states, we also
handle combinations of settings (since the fecparam->fec field is a
bitmask), where auto|rs and auto|baser specify a preferred FEC mode but
will fall back to the other if the cable or link partner doesn't support
it. rs|baser (with or without auto bit) means prefer FEC even where
auto wouldn't use it, but let FW choose which encoding to use.

The case in which we handle a reset from the state where the device is
closed seems to be bugged for all types of reset. For most types of reset
we currently exit the reset routine correctly, but don't set the state to
indicate that we are back in the "closed" state. For some specific cases,
we don't exit the reset routine at all and resetting will cause a closed
device to be opened.
This patch fixes the problem by unconditionally checking the reset_state
and correctly setting the adapter state before returning.

Currently the link state is initialized to "up" when the phy_device is
being created. This is not consistent with the phy state being
initialized to PHY_DOWN.
Usually this doen't do any harm because the link state is updated
once the PHY reaches state PHY_AN. However e.g. if a LAN port isn't
used and the PHY remains down this inconsistency remains and calls
to functions like phy_print_status() give false results.
Therefore change the initialization to link being down.

10GbE Intel Wired LAN Driver Updates 2018-03-12
This series contains updates to ixgbe and ixgbevf only.
Shannon Nelson provides three fixes to the ipsec portion of ixgbe. Make
sure we are using 128-bit authentication, since it is the only size
supported for hardware offload. Fixed the transmit trailer length
calculation for ipsec by finding the padding value and adding it to the
authentication length, then save it off so that we can put it in the
transmit descriptor to tell the device where to stop the checksum
calculation. Lastly, cleaned up useless and dead code.
Tonghao Zhang adds a ethtool stat for receive length errors, since the
driver was already collecting this counter.
Arnd Bergmann fixed a warning about an used variable by "rephrasing" the
code so that the compiler can see the use of the variable in question.
Paul fixes an issue where "HIDE_VLAN" was being cleared on VF reset, so
ensure to set "HIDE_VLAN" when port VLAN is enabled after a VF reset.

Fix up the Tx trailer length calculation. We can't believe the
trailer len from the xstate information because it was calculated
before the packet was put together and padding added. This bit
of code finds the padding value in the trailer, adds it to the
authentication length, and saves it so later we can put it into
the Tx descriptor to tell the device where to stop the checksum
calculation.

Function lan743x_phy_link_status_change assigns pointer 'phy' twice and
this is never read, so it also can be removed.

and then re-assigns the same value into this pointer a little later on

mlxsw_spectrum supports offloading of a tc action mirred egress mirror
to a gretap or an ip6gretap netdevice, which necessitates calls to
functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously
this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on
NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about
picking which modules are absolutely required, and therefore the better
approach is to make mlxsw_spectrum tolerant of absence of one or both of
the GRE flavors.
Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard
matching modularity, and hide the corresponding code in spectrum_span.c
in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as
maybe unused, to muffle warnings if neither GRE flavor is selected,
which seems cleaner than introducing a composite #if.
