WIP patch
i've been playing around with this a bit and it seems like for MSI-X to work,
the driver needs a mapping table set up to tell it which msix tx/rx queues are
enabled.
this patch makes the card work, except there's an odd 1-second delay on all
packets:
64 bytes from 10.1.4.1: icmp_seq=0 ttl=64 time=1000.038 ms
64 bytes from 10.1.4.1: icmp_seq=1 ttl=64 time=1000.037 ms
64 bytes from 10.1.4.1: icmp_seq=2 ttl=64 time=1000.035 ms
64 bytes from 10.1.4.1: icmp_seq=3 ttl=64 time=1000.037 ms
this patch only enables RXQ0; the Linux driver also enables TXQ0, but that
prevents msix from working at all for me; either i'm doing something wrong or
there's another step i missed.
