I'm not sure you suffers from the same problem but there was a Tx checksum offload related bug in msk(4) driver and it was fixed in HEAD. How about applying the diff in CVS rev 1.33 of if_msk? http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/msk/if_msk.c.diff?r1=1.32;r2=1.33;f=h > > Yong-Hyeon Pyun can probably explain what's going on here.
