This is now working for me, testing with the dst MAC being the MAC on the i210.  I set the filter and all the traffic to the destination MAC address gets routed to the chosen RX queue.

However, I am still not getting the raw ethernet source filter to work.  Even back to back with no other system to "confuse" the stream, I set the filter so the source MAC is the same as the MAC on the link partner, send traffic and the traffic bounces around the queues as if the filter is not set.
