bridge: vlan: flush the dynamically learned entries on port vlan delete
Add a new argument to br_fdb_delete_by_port which allows to specify a vid to match when flushing entries and use it in nbp_vlan_delete() to flush the dynamically learned entries of the vlan/port pair when removing a vlan from a port. Before this patch only the local mac was being removed and the dynamically learned ones were left to expire. Note that the do_all argument is still respected and if specified, the vid will be ignored. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.
