Simon Horman b73c85181d netdev-linux: Read packet auxdata to obtain vlan_tid ...

If VLAN acceleration is used when the kernel receives a packet
then the outer-most VLAN tag will not be present in the packet
when it is received by netdev-linux. Rather, it will be present
in auxdata.

This patch uses recvmsg() instead of recv() to read auxdata for
each packet and if the vlan_tid is set then it is added to the packet.

Adding the vlan_tid makes use of headroom available
in the buffer parameter of rx_recv.
