Hello:

This series was applied to netdev/net.git (main)

Since the changes were made to tag_8021q to support imprecise RX for
bridged ports, the tag_sja1105 driver still prefers the source port
information deduced from the VLAN headers for link-local traffic, even
though the switch can theoretically do better and report the precise
source port.

The problem is that the tagger doesn't know when to trust one source of
information over another, because the INCL_SRCPT option (to "tag" link
local frames) is sometimes enabled and sometimes it isn't.

[...]
Here is the summary with links:
  - [v2,net,1/2] net: dsa: sja1105: always enable the INCL_SRCPT option
    https://git.kernel.org/netdev/net/c/b4638af8885a
  - [v2,net,2/2] net: dsa: tag_sja1105: always prefer source port information from INCL_SRCPT

You are awesome, thank you!
