Dual or quad NIC boards?

[Shawn Barnhart]

I'm in the market for a dual or quad NIC board compatible with 4-STABLE
(I'll do 5.x if I have to) for a router/firewall.

Intel make a couple, are they known to be compatible?  The NOS software
compatibilty for the four port model lists it as "FreeBSD (latest kernel)",
whatever that means.

The 4-port one is my preference, although I'm not totally thrilled with the
prices I've seen for it -- nearly $500.  Anyone familiar with any cheaper
versions?
