be interrupt safe?
A device might be deleted after lookup in the SIOCADDRT ioctl but before it's
being used.
Routes to a device begin taken down might be deleted by ax25_rt_device_down
but added by somebody else before the device has been deleted.
Introduce a clear locking strategy. What I've put there is simply an evil
hack to get the code to survive.
Massive amounts of lock_kernel / unlock_kernel are just a temporary solution to
get around the removal of SOCKOPS_WRAP. A serious locking strategy has to be
implemented.
The ax25_rt_find_route synopsys is pervert but I somehow had to deal with
the race caused by the static variable in it's previous implementation.
Implement proper socket locking in netrom and rose.
Check socket locking when ax25_rcv is sending to raw sockets. In particular
ax25_send_to_raw() seems fishy. Heck - ax25_rcv is fishy.

* destination call. Needed for IP routing via digipeater
* Jonathan(G4KLX) Added routing for IP datagram packets.
* Joerg(DL1BKE) Changed routing for IP datagram and VC to use a default

* on route-table overflow anymore.
* Joerg(DL1BKE) Fixed AX.25 routing of IP datagram and VC, new ioctl()

* AX.25 035 Frederic(F1OAT) Support for pseudo-digipeating.
