This occurs in all versions of the driver I've tested. My 8139too
driver in kernel 2.4.x minimizes this case for some chip revisions, but
doesn't solve the bug completely either.
I have a feeling it is incomplete handling of one or both RxFifoOverflow
and TxErr errors, causing the "freeze" which appears not only in the
Linux drivers, but the OpenBSD driver as well.
