I know you said you couldn't do this, but it may well be very useful to 
compare this to the output when using the built in FreeBSD driver as it 
may highlight a key difference.

I'm thinking given the ages of the Realtek driver we could be looking at 
a different operational mode, different MSI-X count etc.
