Doing
kldload cxgbe
ifconfig cxgbe
doesn't show an up state:
# kldstat -v | grep cxgbe && echo found || echo not found
not found
# kldload if_cxgbe
# kldstat -v | grep cxgbe && echo found || echo not found

Only if I do an ifconfig up does the driver actually detect link-up:
root@wf158:~ # ifconfig cxgbe1 up
root@wf158:~ # ifconfig cxgbe0 up
root@wf158:~ # ifconfig cxgbe1
