sys/net : if_ethersubr.c if_gre.c if_pppx.c pipex.c
pipex.h pipex_local.h
sys/netinet : ip_gre.c udp_usrreq.c
Log message:
The "ifq_set_maxlen(..., 1);" hack we use to enforce pipex(4) related
(*if_qstart)() be always called with netlock held doesn't work anymore
with PPPOE sessions.
Introduce `pipex_list_mtx' mutex(9) and use it to protect global pipex(4)
lists and radix trees.
Protect pipex(4) `session' dereference with reference counters, because we
could sleep when accessing pipex(4) from ioctl(2) path, and this is not
possible with mutex(9) held.
