Nice.

Point taken. Thanks.

spinlock + msleep in __mdio_cmd()... Completely stupid.

The patchkit of the day should fix these issues:
http://www.zoreil.com/~romieu/sis190/20050706-2.6.13-rc1/patches

Tarball:
http://www.zoreil.com/~romieu/sis190/20050706-2.6.13-rc1.tar.bz2

Please shake it. You should be able to modify the set of displayed
messages with ethtool.

I'd appreciate if you could check the allowed frame size range, say
ping -s 1468 ... ping -s 1473 to compare with Lars's results.

You can add something like a ping -q -l 48 -s 64 -f to your tests and
increase the 48 and NUM_{RX/TX}_DESC but I am not sure that the remote
8139 will be able to go terribly far. If it performs well, pktgen
could be useful too.

Lars, can you describe the second host that you have used so far for
the tests:
- which nic ?
- which kernel ?

(on an unrelated note, something enabled the "send mail as html" checkbox
in your mail user agent: you may consider removing it).
