Intel. Broadcom. That's what we use here w/o any issues; however, there are some Intel NICs that are *not* able to handle Jumbo Frames due to an internal design glitch.
Seconded. I have a load of Intel 82576 and 82571EB's, and there have been no issues at all, including with Jumbo frames.
Please take note that some Intel 1G nics do not have jumbo frame support at all. So you won't have issues with jumbo frames either way. The question is whether there is jumbo frame support.
The Intel NICs that I mentioned, 82576 and 82571EB, are both in use in DRBD replication links with an MTU of 9000. We usually configure each such link as a point-to-point bonding pair (balance-rr), and get 1.95 Gb/s throughput with iperf, and about 165 MB/sec with drbd (but of course the latter is disk dependent). CentOS 5.5, x86_64, Dell PE2900 servers. Solid.
