Actually...
I'm less enamoured with the PNIC as a tulip clone than I used to be.
Basically, the revision found on basically all of the NetGear cards
has a HORRIBLE bug in the receive engine, when the chip is in
promiscuous mode (think: your DHCP server machine). The work-around
employed by other drivers for the bug means a huge performance hit.
There may be another way to work around it... still investigating.
Really unfortunate.
