I see transmit underrun erros all the time on my sf card. They don't
seem to impact my performance. But the rtk chipset sucks compared to
the sf, so you may want to explicitly set it higher (probably means
maintaining local changes to a few things under src/sys/dev/pci/if_*).

Are you actually seeing performance problems because of it?

If you just don't want the log messages around, you can tell the
driver to be less noisy (again, local changes).

That's evil. But it smells like an NFS problem, not a NIC one.

What specific arguments are you giving to -{r,w}?

I'd recommend replacing the NIC just on the horrid experience I've
had with the RealTek chipset. But that's a somewhat orthogonal
