As a follow up for:
74cf3d16d8e9 ("tests: shell: add vlan match test case")
Add basic test for q-in-q matching support.
Signed-off-by: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>

NOTE: `vlan type ip` matches at offset 20 at link-layer.
But 'ip saddr' matching does not work with q-in-q, I suspect an issue with
skb_network_header() not set to IP address when two vlan tags are present.
With one single vlan tag it works, because vlan tag ends up in the vlan
offload fields of the skbuff.
That is why I have picked this:
+ ether type 8021ad vlan id 10 vlan type 8021q vlan id 100 vlan type ip counter
^----------^
instead of ip saddr until this is fixed.
