thorpej 9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

thorpej 65c188b3c7 Make length and offset fields unsigned. From Kevin M. Lahey <kml@nas.nasa.gov> 
Add a counter to IP stats, to count packets which are discarded on the
grounds that they are too large.

is 08899f4a1b Fix a mbuf leak in ip_output(). 
Scenario: If ip_insertoptions() prepends a new mbuf to the chain, the
bad: label's m_freem(m0) still would free only the original mbuf chain
if the transmission failed for, e.g., no route to host; resulting in
one lost mbuf per failed packet. (The original posting included a
demonstration program).

Original report of this bug was by jinmei@isl.rdc.toshiba.co.jp
(JINMEI Tatuya) on comp.bugs.4bsd.

perry 17fcad6b2c commit fix in pr 2772 -- the IP input code was assuming that the 
reserved (must be zero) flag must necessarily be zero. We now define
an IP_RF (by analogy to IP_DF and IP_MF) and mask it out when necessary.

explorer f5a52c4260 Move an #ifdef _KERNEL up above all the packet filter stuff. This 
could very well break the packet filter stuff, but it will make things
like rcp.c compile, and rcp.c should not need to include sys/mbuf.h
to do so...
