Recently I have finally got the 950622-SNAP and found that the ep driver
in it is enough old. Commit please this patch to -current. It does:
- understands 3C509 cards in "plug-n-play" mode
- understands the cards after soft reboot from MS-DOS
- doesn't conflict with ie driver
- has multicast support
