H A Dipoib.hdiff 9319562b86a6df09b762849ac00646968ff6e9af Tue Mar 15 16:47:26 CET 2016 Hans Petter Selasky <hselasky@FreeBSD.org> Fix witness panic in the ipoib_ioctl() function when unloading the
ipoib module.

The bpfdetach() function is trying to turn off promiscious mode on the
network interface it is attached to while holding a mutex. The fix
consists of ignoring any further calls to the ipoib_ioctl() function
when the network interface is going to be detached. The ipoib_ioctl()
function might sleep.
