  Modified files:
    sys/pci              if_dc.c if_dcreg.h 
  Log:
  Avoid an unnecessary copy of a packet if it is already in a single mbuf.
  Introduce an additional device flag for those NICs which require the
  transmit buffers to be aligned to 32-bit boundaries.
  
  (the equivalen fix for STABLE is slightly simpler because there are
  no supported chips which require this alignment there.)
