State-Changed-Why: 
This is known issue, a possible workaround would be to disable TSO on fxp(4).
A true fix is to apply this patch:

        # cd /tmp
        # fetch -o fxp.tso.patch 
"http://svn.freebsd.org/viewvc/base/head/sys/dev/fxp/if_fxp.c?r1=190982&r2=188176&view=patch";
        # cd /usr/src/sys/dev/fxp
        # patch -p4 < /tmp/fxp.tso.patch

Rebuild, install kernel and reboot.
