bridge: Fix flushing of dynamic FDB entries
The following commands should result in all the dynamic FDB entries
being flushed, but instead all the non-local (non-permanent) entries are
flushed:
# bridge fdb add 00:aa:bb:cc:dd:ee dev dummy1 master static
# bridge fdb add 00:11:22:33:44:55 dev dummy1 master dynamic
# ip link set dev br0 type bridge fdb_flush
# bridge fdb show brport dummy1
00:00:00:00:00:01 master br0 permanent
33:33:00:00:00:01 self permanent
01:00:5e:00:00:01 self permanent
This is because br_fdb_flush() works with FDB flags and not the
corresponding enumerator values. Fix by passing the FDB flag instead.
After the fix:
# bridge fdb add 00:aa:bb:cc:dd:ee dev dummy1 master static
# bridge fdb add 00:11:22:33:44:55 dev dummy1 master dynamic
# ip link set dev br0 type bridge fdb_flush
# bridge fdb show brport dummy1
00:aa:bb:cc:dd:ee master br0 static
00:00:00:00:00:01 master br0 permanent
33:33:00:00:00:01 self permanent
01:00:5e:00:00:01 self permanent
