You remove a filter by setting it to 0 on that queue. Works for either MAC or VLAN.

Setting a MAC filter doesn't blow away the VLAN filter, or vice-versa. So just run 'ip' twice to set the filters. Our hardware does it too, and it works fine for me:

$ ip link set eth1 queue 1 mac 00:11:22:33:44:55
$ ip link set eth1 queue 1 vlan 10
