2021-06-09netdevsim: delete unnecessary debugfs checkingDan Carpenter
In normal situations where the driver doesn't dereference "nsim_node->ddir" or "nsim_node->rate_parent" itself then we are not supposed to check the return from debugfs functions. In the case of debugfs_create_dir() the check was wrong as well because it doesn't return NULL, it returns error pointers.

2021-06-09net: dsa: b53: Do not force CPU to be always taggedFlorian Fainelli
Commit ca8931948344 ("net: dsa: b53: Keep CPU port as tagged in all VLANs") forced the CPU port to be always tagged in any VLAN membership. This was necessary back then because we did not support Broadcom tags for all configurations so the only way to differentiate tagged and untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU port into being always tagged. With most configurations enabling Broadcom tags, especially after 8fab459e69ab ("net: dsa: b53: Enable Broadcom tags for 531x5/539x families") we do not need to apply this unconditional force tagging of the CPU port in all VLANs. A helper function is introduced to faciliate the encapsulation of the specific condition requiring the CPU port to be tagged in all VLANs and the dsa_switch_ops::untag_bridge_pvid boolean is moved to when dsa_switch_ops::setup is called when we have already determined the tagging protocol we will be using.

This tweaks several small places to improve the data access in fast path: * Remove duplicates of first_interrupt flag and surround it with WRITE/READ_ONCE macros: The flag is used to detect HW disorders in its interrupt communication with the driver. The flag is set when an interrupt is received and used in the health check function (ena_timer_service()) to help it find irregularities. * Reorder some fields in ena_napi struct to take better advantage of cache access pattern. * Move XDP TX queue number to a variable to save its calculation for every packet. * Use likely in a condition to improve branch prediction The 'first_interrupt' and 'interrupt_masked' flags were moved to reside in the same cache line as the first fields of 'napi' struct. This placement ensures that all memory accessed during upper-half handler reside in the same cacheline (napi_schedule_irqoff() only accesses 'state' and 'poll_list' fields which are at the beginning of napi struct).

2021-06-08mlxsw: thermal: Read module temperature thresholds using MTMP registerMykola Kostenok
mlxsw_thermal_module_trips_update() is used to update the trip points of the module's thermal zone. Currently, this is done by querying the thresholds from the module's EEPROM via MCIA register. This data does not pass validation and in some cases can be unreliable. For example, due to some problem with transceiver module. Previous patch made it possible to read module's temperature and thresholds via MTMP register. Therefore, extend mlxsw_thermal_module_trips_update() to use the thresholds queried from MTMP, if valid. This is both more reliable and more efficient than current method, as temperature and thresholds are queried in one transaction instead of three.

2021-06-08mlxsw: spectrum_router: Remove abort mechanismAmit Cohen
The abort mechanism was introduced in commit 8e05fd7166c6 ("fib: hook IPv4 fib for hardware offload") with the purpose of falling back to software-based routing in case of a route programming error in hardware. The process is irreversible and requires users to reload the offloading driver or reboot the machine. While this approach might make sense in theory, it makes very little sense in practice. In the case of high speed ASICs such as the Spectrum ASIC, the abort mechanism effectively kills the machine upon a non-fatal error such as a route programming error. Such an extreme policy does not belong in the kernel, especially when user space can simply try to reprogram the route following the RTM_NEWROUTE failure notification. Therefore, remove the abort mechanism.

The SJA1110 contains two types of integrated PHYs: one 100base-TX PHY and multiple 100base-T1 PHYs. The access procedure for the 100base-T1 PHYs is also different than it is for the 100base-TX one. So we register 2 MDIO buses, one for the base-TX and the other for the base-T1. Each bus has an OF node which is a child of the "mdio" subnode of the switch, and they are recognized by compatible string.

The SJA1110 is basically an SJA1105 with more ports, some integrated PHYs (100base-T1 and 100base-TX) and an embedded microcontroller which can be disabled, and the switch core can be controlled by a host running Linux, over SPI. This patch contains: - the static and dynamic config packing functions, for the tables that are common with SJA1105 - one more static config tables which is "unique" to the SJA1110 (actually it is a rehash of stuff that was placed somewhere else in SJA1105): the PCP Remapping Table - a reset and clock configuration procedure for the SJA1110 switch. This resets just the switch subsystem, and gates off the clock which powers on the embedded microcontroller. - an RGMII delay configuration procedure for SJA1110, which is very similar to SJA1105, but different enough for us to be unable to reuse it (this is a pattern that repeats itself) - some adaptations to dynamic config table entries which are no longer programmed in the same way. For example, to delete a VLAN, you used to write an entry through the dynamic reconfiguration interface with the desired VLAN ID, and with the VALIDENT bit set to false. Now, the VLAN table entries contain a TYPE_ENTRY field, which must be set to zero (in a backwards-incompatible way) in order for the entry to be deleted, or to some other entry for the VLAN to match "inner tagged" or "outer tagged" packets. - a similar thing for the static config: the xMII Mode Parameters Table encoding for SGMII and MII (the latter just when attached to a 100base-TX PHY) just isn't what it used to be in SJA1105. They are identical, except there is an extra "special" bit which needs to be set. Set it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
