A while back I committed patches to use bpf_detach(), which elminated the
struct ifnet pointer in the bpf described at detach time.  This removed
most of the panics I experience on ejecting pccards.  This should be in
5.0-CURRENT and 4.1-STABLE.  If you're still experiencing panics, we
should track it down some more as presumably there is another reference
(it could also be a race condition, or in-use mbuf during detach?)
