the 2.4 driver provides a mode which sends ARP packets
to test the link (far more reliable than MII), and the
appropriate ioctl for the NIC switch-over you need. It
is available to user through ifenslave -c bond0 eth0
for example.

well, it works for me each time I download a new
release, but I don't have prod servers on it to test
for a long time, nor have I passed all the intensive
tests that Constantine Gavrilov did when I was working
on 2.2. BTW, the last release (20011026) seems to have
a buggy ifenslave which activates all the NICs flags
(to be confirmed, just seen this today and replaced
with the previous one). If this is confirmed, I'll
mail
Chad about this problem.
If there are still people interested in 2.2, I'll try
to find some time to back-port the switch-over ioctl
from 2.4.
Regards,
Willy
