  Log:
  Check the alignment of the IP header before passing the packet up to the
  packet filter. This would cause a panic on architectures that require strict
  alignment such as sparc64 (tier1) and ia64/ppc (tier2).
  
  This adds two new macros that check the alignment, these are compile time
  dependent on __NO_STRICT_ALIGNMENT which is set for i386 and amd64 where
  alignment isn't need so the cost is avoided.
  
   IP_HDR_ALIGNED_P()
   IP6_HDR_ALIGNED_P()
  
  Move bridge_ip_checkbasic()/bridge_ip6_checkbasic() up so that the alignment
  is checked for ipfw and dummynet too.
