sys/netinet : ip_output.c
Log message:
Prevent a NULL derefernce in ip_output().
A race can happen if a task, like the watchog, sleeps too long keeping
an ifp reference while the interface is detached. In this case a TCP
timer will try to send packets with a cached route. Since the ifp is
being detached if_get(9) returns NULL.
