I recently setup a OpenBSD bridging firewall to protect an area of the
network.
I'm limited to about 40MB per second throughput due to small frame tcp/ip
issues.
I'd like to up it.
I see my choices as either upping frame size (unlikely, large infrastructure
change) or using a full TOE implmentation ethernet card.

But I don't see any that are not specially Sun or MS (blech).

All TOE I see is partial, ie: just checksum offload. I want the smaller
packets to be aggregated before a kernel interrupt is kick off.

Anybody aware of any cards / drivers that will do what I want?

My OS preferences (in order) are OpenBSD, (FreeBSD|NetBSD), Linux (Debian,
then RH), and then Solaris.

Thanks.

Initial driver support was a nightmare, but that was years ago.
I'm currently using a 6 port Silicom nroadcom based card for my sniffer/ntop box.

Thanks.
