  Log:
  Conditionally acquire Giant based on debug.mpsafenet around entry points
  from if_re taskqueue and other potentially Giant-free spots.  If we don't
  do this, Giant may not be held entering KAME IPSEC, etc.
  
  This problem appeared in FreeBSD 6.2 as a result of a move to fast
  interrupts, and does not exist in 7.x due to not having debug.mpsafenet.
