I ran into a strange problem when manually loading a network driver
after RELENG_11 box starts up with a routing daemon already running.
If I have zebra running (just a few static routes) and then try and do a
kldload if_cxgb, the box panics. If I boot the box, load the nic's
driver and then start zebra, all is fine.
At first, I thought it might be a firmware issue, but I updated the
NIC's firmware and the same behaviour. Not sure if this is specific to
the chelsio or if any kldload of a NIC driver will do.
