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.
