The X520 should have no problems hashing on a single VLAN tagged frame.
However the VLAN will not be a part of the RSS hash. The only
components of the hash are the IPv4/IPv6 source and destination
addresses, and if the flow is TCP then the port numbers.
I would recommend testing with something like the "netperf -t TCP_CRR"
test which should open a number of ports and spread traffic out between
multiple queues.
Thanks,
Alex
