  Branch:      sys/netinet  RELENG_2_2
  Modified:    sys/netinet  ip_input.c
  Log:
  Roll ip_sum mods into 2.2:
  
      Don't zero ip->ip_sum during sum validation.  This should only
      affect programs that sit on top of divert(4) sockets.  The
      multicast routing code already unconditionally zeros the sum
      before recalculating.
  
      Any code that unconditionaly sums a packet without first zeroing
      the sum (assuming that it's already zero'd) will break.  No such
      code seems to exist.
