netdev-linux: double tagged packets should use 0x88a8
We need to check if a packet is double tagged. If so make sure to push
0x88a8 instead of 0x8100. Without this a simple port redirect of 802.1ad
frames means the outer tag gets translated from 0x88a8 to 0x8100 by the
This only affected kernels that don't use TP_STATUS_VLAN_TPID_VALID,
which is kernels < 3.14.
