I think the odds of getting into the tree are pretty good. I certainly plan to give it a shot. The firmware is basically identical to what we currently have in the tree (12.4.11 plus some fixes Bill Paul picked out from 12.4.13), plus the header splitting patches. There have been some newer firmware releases, up to 12.4.18 I think, but I haven't yet been able to get anything from 3Com. I know 12.4.18 at least fixes some checksum offloading issues in a few strange cases. > Thanks again for keeping this alive, > > Drew Ken -- Kenneth Merry ken@kdm.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
