What exactly is a transmit underflow anyways?

Thanks in advance,

Hello,

I never really noticed this before (mainly because I leave my serial
console off all the time), but this is the message I keep getting on my
console.  What exactly does this mean?

The computer in question is running NetBSD/macppc 1.4.1 with a Sonic
CommSlot II 10BaseT ethernet card connected via crossover cable to a PC
running Linux with a RealTek RTL8139 (100BaseTX, PCI).

Another thing is that occasionally it seems that the ethernet card on the
Macintosh sort of "freezes" once in a while and I have to reboot;
sometimes just the Macintosh and sometimes both Mac and PC.  Very
strange...

Any help would be greatly appreciated,
