848a25c773 Remove a recursion protection, which we inherited from splnet() netgraph times. 
Now several threads may write data to ng_ksocket. Locking of socket is done in
sosend().

843cfd5ae0 Make WITNESS happier: 
- refactor ngd_constructor, so that make_dev() is called without
  any locks held, since it mallocs memory with M_WAITOK flag.
- rename global mtx, to have name different to per-node mtx

cefddd662e Add new netgraph control message NGM_ETHER_DETACH, which actually 
removes netgraph node and unwraps Ethernet interface.

This gives us ability to unload ng_ether.ko, when all interfaces
are detached, making ng_ether(4) developers happy.

b07785ef50 When netgraph(4) was converted to use mbuf_tags(9) instead of meta-data 
a definite setup was broken: two ng_ksockets are connected to each other,
connect()ed to different remote hosts, and bind()ed to different local
interfaces. In this case one ng_ksocket is fooled with tag from the other
one.

Put node id into tag. In rcvdata method utilize tag only if it has our
own id inside or id equals zero. The latter case is added to support
packets send by some third, not ng_ksocket node.

with net byte order. Change byte order to net in ng_ipfw_input(), change

195cf61776 In revision 1.29 timeout() was converted to ng_callout(). 
The difference is that the callout function installed via the
ng_callout() method is guaranteed to NOT fire after the shutdown
method was run (when a node is marked NGF_INVALID).  Also, the
shutdown method and the callout function are guaranteed to NOT
run at the same time, as both require the writer lock.  Thus
we can safely ignore a zero return value from ng_uncallout()
(callout_stop()) in shutdown methods, and go on with freeing
the node.

The said revision broke the node shutdown -- ng_bridge_timeout()
is no longer fired after ng_bridge_shutdown() was run, resulting
in a memory leak, dead nodes, and inability to unload the module.
Fix this by cancelling the callout on shutdown, and moving part
responsible for freeing a node resources from ng_bridge_timer()
to ng_bridge_shutdown().

6aa1da2917 In case of various tunneling protocols, mbuf may pass several interfaces

However, it will enter ng_iface soon with another index. So let in_ifIndex
