Vladimir Oltean says:

====================
Fix 2 DSA issues with vlan_filtering_is_global

This patch set fixes 2 issues with vlan_filtering_is_global switches.

Both are regressions introduced by refactoring commit d0004a020bb5
("net: dsa: remove the "dsa_to_port in a loop" antipattern from the
core"), which wasn't tested on a wide enough variety of switches.

Tested on the sja1105 driver.
