2.6.21 seems to have fixed the stability issues I was seeing when using
the skge driver with the older sk98xx dual port fiber cards. There is
still one more lingering oddness: if I have *two* dual port cards in a
system, say eth2-5, I see traffic on eth2, eth3, and eth5, but nothing
on eth4. This seems to be consistent accross a couple of systems I've
tested; only the first card's second interface sees packets (e.g., with
tcpdump). If I reboot with the sk98lin driver on the same kernel I see
all traffic, as expected.
Are the statistics changing? ie. ethtool -S eth4 and ifconfig eth4
Ok, I ran this for a lot longer and it seems less consistent than it did
at first. It now appears that there is no correlation between a NIC not
working and its order. In some cases the NICs both come up ok, and see
traffic for a while. I left one example running over the weekend, and
neither interface on one card was seeing traffic, and the interface
counters weren't increasing. In another case, one interface on one NIC
worked for a short period of time, then stopped. The interface counters
would increase by a few packets every 30 seconds or so. Any kind of
ethtool operation (e.g., ethtool -A eth4 autoneg off rx off tx off)
would cause the interface to start seeing traffic again, then eventually
go back to seeing only a few packets every few seconds.
