Add byteswapping.  Original version partially worked on PPC with Net2280,
this version applies to the latest RNDIS code but hasn't been retested on
big-endian.  Ping should be working in at least one one direction.

Also added a handful of other things from my BK:  track suspend/resume
(to eventually implement wake-on-lan), give a better rndis error
message, and add missing declarations for PM-related OIDs (usage is
#ifdeffed out by previous patch).
