Be there 2 switches spi/spi2.0 and spi/spi2.1 in a cross-chip setup,
both under the same VLAN-filtering bridge, both in the
SJA1105_VLAN_BEST_EFFORT state.
If we try to change the VLAN state of one of the switches (to
SJA1105_VLAN_FILTERING_FULL) we get the following error:
devlink dev param set spi/spi2.1 name best_effort_vlan_filtering value
false cmode runtime
[ 38.325683] sja1105 spi2.1: Not allowed to overcommit frame memory.
L2 memory partitions and VL memory partitions share the
same space. The sum of all 16 memory partitions is not
allowed to be larger than 929 128-byte blocks (or 910
with retagging). Please adjust
l2-forwarding-parameters-table.part_spc and/or
vl-forwarding-parameters-table.partspc.
[ 38.356803] sja1105 spi2.1: Invalid config, cannot upload
This is because the spi/spi2.1 switch doesn't support tagging anymore in
the SJA1105_VLAN_FILTERING_FULL state, so it doesn't need to have any
retagging rules defined. Great, so it can use more frame memory
(retagging consumes extra memory).
But the built-in low-level static config checker from the sja1105 driver
says "not so fast, you've increased the frame memory to non-retagging
values, but you still kept the retagging rules in the static config".
So we need to rebuild the VLAN table immediately before re-uploading the
static config, operation which will take care, based on the new VLAN
state, of removing the retagging rules.

Intel Wired LAN Driver Updates 2020-05-28

Takashi Iwai, from SUSE, replaces some uses of snprintf() with

Jason Yan, from Huawei, converts '==' expression to bool to resolve

igb and i40e drivers.
YueHaibing, from Hauwei, cleans up dead code in ixgbe driver.
Sasha cleans up more dead code which is not used in the igc driver.
Added receive error counter to reflect the total number of non-filtered
packets received with errors. Fixed a register define name to properly

Andre updates the igc driver to reject NFC rules that have multiple
matches, which is not supported in i225 devices. Updates the total
number of NFC rules supported and added a code comment to explain what
is supported.
Punit Agrawal, from Toshiba, relaxes the condition to trigger a reset
