   4 Subject: net: dsa: Move VLAN filtering syncing out of dsa_switch_bridge_leave
   5
   6 Most of dsa_switch_bridge_leave was, in fact, dealing with the syncing
   7 of VLAN filtering for switches on which that is a global
   8 setting. Separate the two phases to prepare for the cross-chip related
   9 bugfix in the following commit.
