====================
Dynamic toggling of vlan_filtering for SJA1105 DSA

This patchset addresses a limitation in dsa_8021q where this sequence of
commands was causing the switch to stop forwarding traffic:

  ip link add name br0 type bridge vlan_filtering 0
  ip link set dev swp2 master br0
  echo 1 > /sys/class/net/br0/bridge/vlan_filtering
  echo 0 > /sys/class/net/br0/bridge/vlan_filtering

The issue has to do with the VLAN table manipulations that dsa_8021q
does without notifying the bridge layer. The solution is to always
restore the VLANs that the bridge knows about, when disabling tagging.
