Log message:
pf_socket_lookup() calls in_pcbhashlookup() in the PCB layer. To
run pf in parallel, make parts of the stack MP safe. Protect the
list and hashes in the PCB tables with a mutex.
Note that the protocol notify functions may call pf via tcp_output().
As the pf lock is a sleeping rw_lock, we must not hold a mutex. To
solve this for now, collect these PCBs in inp_notify list and protect
it with exclusive netlock.
