Writing large files over a socket with SSH, SMB, nc to that mountpoint results
in tremendous breakdowns of transfer speed down to kilobytes per second. SSH
becomes unresponsive. dmesg says over and over again:

The same test was performed with another NIC in that system: rl0 (Realtek
8139). No performance degregation was found.
Additionally, 10baseT and half-duplex where tested with some positive results.
Though, dropouts came a bit later, but still unacceptable to use.
Similar issues were already reported some years ago:

It seems to be driver-related.
