It seems like there's a big consensus that HEAD has some good new fixes. Looking at this: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/e1000/if_em.c There's a pretty big commit to HEAD in rev 1.58 on Sep 27 that's marked "MFC: a week" but it doesn't look like anything's been MFC'd since. (And several other revisions that look more experimental have since gone into HEAD.) We've been seeing some weird issues with em devices under high load and if these changes in 1.58 are ready for STABLE we'd love to test them live. So this is a beg... if the relevant committers are out here, can that MFC go through soon? Or if it can't, or I'm reading the logs wrong, please explain. Thanks in advance.
