Here is updated patch.
http://www.kr.freebsd.org/~yongari/em.patch.0419

The new patch includes jmg's suggestion and supports JUMBO frames.
Though OpenBSD's aligment code works well I noticed it suffers
from poor performance. So I used simple mbuf prepend method which
is slightly faster than that of OpenBSD's code. Of course, best
performance would be obtained when JUMBO frame is not used at all. :-(
