dude, I just went though the 3c590 problems with the very same snap, I
kept on getting FIFO overruns with any mtu over 200, the driver is messed
up because 3com slightly changed the spec of the 3c590 after initial
release, from what I was told. I traded it in for an SMC PCI EtherPower
and it works great. I did try the 3com on a 2.1.0 release machine and
had the same problems. Since the SMC uses the de driver (it is the same
digital chipset of about 10 PCI cards that has been supported well by
FBSD for awhile.
Get the SMC, its cheaper and it works VERY well.
Notice that the vx driver isn't even running in multicast mode?
