Merge branch '8021ad'

Patrick McHardy says:

====================
The following patches add support for 802.1ad (provider tagging) to the
VLAN driver. The patchset consists of the following parts:

- renaming of the NET_F_HW_VLAN feature flags to indicate that they only
  operate on CTAGs

- preparation for 802.1ad VLAN filtering offload by adding a proto argument
  to the rx_{add,kill}_vid net_device_ops callbacks

- preparation of the VLAN code to support multiple protocols by making the
  protocol used for tagging a property of the VLAN device and converting
  the device lookup functions accordingly

- second step of preparation of the VLAN code by making the packet tagging
  functions take a protocol argument

- introducation of 802.1ad support in the VLAN code, consisting mainly of
  checking for ETH_P_8021AD in a couple of places and testing the netdevice
  offload feature checks to take the protocol into account

- announcement of STAG offloading capabilities in a couple of drivers for
  virtual network devices

The patchset is based on net-next.git and has been tested with single and
double tagging with and without HW acceleration (for CTAGs).
