Subject: [PATCH 5.10 1/2] net: dsa: Move VLAN filtering syncing out of
dsa_switch_bridge_leave
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 381a730182f1d174e1950cd4e63e885b1c302051 upstream.
Most of dsa_switch_bridge_leave was, in fact, dealing with the syncing
of VLAN filtering for switches on which that is a global
setting. Separate the two phases to prepare for the cross-chip related
bugfix in the following commit.
