You mention re0 being renamed to xn0.
I couldn't find any device xn or xn0 in FreeBSD 11-current, though I found xe and xen.
I figured if it were in 10-STABLE, it would also be in 11-HEAD.
For a moment, I thought maybe the reason why I couldn't connect Ethernet on MSI Z77 MPOWER motherboard was needing to use a driver other than re, but nothing so simple.
There is still device re.
Did you make a typo with xn0?
I also wonder if the best way to upgrade to FreeBSD 10 is to jump to 11-HEAD, am seriously considering that.
