samples/bpf: xdpsock: Add VLAN support for Tx-only operation
In multi-queue environment testing, the support for VLAN-tag based
steering is useful. So, this patch adds the capability to add
VLAN tag (VLAN ID and Priority) to the generated Tx frame.
To set the VLAN ID=10 and Priority=2 for Tx only through TxQ=3:
$ xdpsock -i eth0 -t -N -z -q 3 -V -J 10 -K 2
If VLAN ID (-J) and Priority (-K) is set, it default to
VLAN ID = 1
VLAN Priority = 0.
For example, VLAN-tagged Tx only, xdp copy mode through TxQ=1:
$ xdpsock -i eth0 -t -N -c -q 1 -V
