I think the problem, you've described isn't the same problem as in kern/78791.
I haven't used this card in a long time and i don't know if TX/RX
checksum offloading is supported in the FreeBSD driver. Just to sum up
my findings.
Checksum offloading is bugged, even on windows drivers. Disabling
checksum offloading has always resulted in much better performance.
Also, when you say using "100baseTX-FDX" you mean between the servers
and not via a switch, right?
