History
Andre Oppermann 06bb56f43c Optimize IP fastforwarding some more: 
o New function ip_findroute() to reduce code duplication for the
  route lookup cases. (luigi)

o Store ip_len in host byte order on the stack instead of using
  it via indirection from the mbuf.  This allows to defer the host
  byte conversion to a later point and makes a quicker fallback to
  normal ip_input() processing. (luigi)

o Check if route is dampned with RTF_REJECT flag and drop packet
  already here when ARP is unable to resolve destination address.
  An ICMP unreachable is sent to inform the sender.

o Check if interface output queue is full and drop packet already
  here.  No ICMP notification is sent because signalling source quench
  is depreciated.

o Check if media_state is down (used for ethernet type interfaces)
  and drop the packet already here.  An ICMP unreachable is sent to
  inform the sender.

o Do not account sent packets to the interface address counters.  They
  are only for packets with that 'ia' as source address.

o Update and clarify some comments.
