  Modified:    sys/netinet  ip_input.c
  Log:
  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.
