	syssrc/sys/dev/pci: if_sip.c if_vr.c

Log Message:
Be a little nicer about memory usage:
* Don't allocate receive buffers until the interface is actually brought
  up, and release all of them if the interface is taken down.
* Add a knob (defaults to off) which will copy an incoming packet to
  a single header mbuf if it is small enough to fit in one, rather than
  burning an entire cluster on it.  Note that this change will be mostly
  moot if/when sbcompress() it changed to handle compressing clusters.
