The D-Link DFE530TX NIC, which is based on the VIA Rhine-II chip,
doesn't seem to work properly when receiving data fast. Sending isn't a
problem.

eth0: VIA VT6102 Rhine-II at 0xd400, 00:50:ba:f1:b5:d3, IRQ 10.
eth0: MII PHY found at address 8, status 0x7829 advertising 01e1 Link
      40a1.

when doing 'wget http://a-computer-on-the-same-hub/abt-1MB-file -O /dev/null' I get the following on 2.4.0-test11 (and propably with all the other test-kernels):

---
Nov 21 15:37:02 FOO kernel: NETDEV WATCHDOG: eth0: transmit timed out
Nov 21 15:37:02 FOO kernel: eth0: Transmit timed out, status 0000, 
                            PHY status 782d, resetting...
---

and then it starts looping until something like 'ifconfig eth0 down; sleep 10; ifconfig eth0 up; route add default gw ...' is done. in beetween the first message and the ifconfig-stuff, network is completely unusable, which is quite annoying I don't happen to be on the console.

the very same thing appears on 2.2 kernels with the becker's module from http://www.scyld.com/network/via-rhine.html, but without the NETDEV_WATCHDOG-stuff.
