bb2e8627df Use the correct length from the mbuf header instead of the one from
the IP header (this would not work for bridged packets).
This has been fixed long ago in the 2.2 branch.

Move the Olicom token ring driver to the officially sanctionned location of
/sys/contrib. Also fix some brokenness in the generic token ring support.

Be warned that if_dl.h has been changed and SOME programs might
like recompilation.

2f3574b0d4 Add support for stealth forwarding (forwarding packets without touching
their ttl). This can be used - in combination with the proper ipfw
incantations - to make a firewall or router invisible to traceroute
and other exploration tools.

This behaviour is controlled by a sysctl variable (net.inet.ip.stealth)
and hidden behind a kernel option (IPSTEALTH).

16c8d9e8d0 World, I'd like you to meet the first FreeBSD token Ring driver.

This patch also adds support to tcpdump to decode packets on tokenring.

433e0009a0 After wading in the cesspool of ip_input for an hour, I have managed to
convince myself that nothing will break if we permit IP input while
interface addresses are unconfigured.  (At worst, they will hit some
ULP's PCB scan and fail if nobody is listening.)  So, remove the restriction
that addresses must be configured before packets can be input.  Assume
that any unicast packet we receive while unconfigured is potentially ours.

30dc804fc7 If arpresolve() gets passed a route with a null llinfo, call
arplookup() to try again.  This gets rid of at least one user's
 "arpresolve: can't allocate llinfo" errors, and arplookup() gives
 better error messages to help track down the problem if there really
 is a problem with the routing table.

09f08ede8d Partial fix for when ipfw is used with bridging. Bridged packets
have all fields in network order, whereas ipfw expects some to be
in host order. This resulted in some incorrect matching, e.g. some
packets being identified as fragments, or bandwidth not being
correctly enforced.
NOTE: this only affects bridge+ipfw, normal ipfw usage was already
correct).
