Subject: [PATCH net 00/14] VLAN fixes for Ocelot driver

This is a collection of patches I've gathered over the past several
months.

Patches 1-6/14 are supporting patches for selftests.

Patch 9/14 fixes PTP TX from a VLAN upper of a VLAN-aware bridge port
when using the "ocelot-8021q" tagging protocol. Patch 7/14 is its
supporting selftest.

Patch 10/14 fixes the QoS class used by PTP in the same case as above.
It is hard to quantify - there is no selftest.

Patch 11/14 fixes potential data corruption during PTP TX in the same
case as above. Again, there is no selftest.

Patch 13/14 fixes RX in the same case as above - 8021q upper of a
VLAN-aware bridge port, with the "ocelot-8021q" tagging protocol. Patch
12/14 is a supporting patch for this in the DSA core, and 7/14 is also
its selftest.

Patch 14/14 ensures that VLAN-aware bridges offloaded to Ocelot only
react to the ETH_P_8021Q TPID, and treat absolutely everything else as
VLAN-untagged, including ETH_P_8021AD. Patch 8/14 is the supporting
selftest.
