Doug Ambrisko b376d47740 - Fixes for suspend/resume code (MPI-350) 
- Cache temp. keys so they are preserved across suspend/resume (MPI-350)
- Reads and writes are real fast to the MPI-350 causing early timeouts so
  wait do some DELAYs to slow things down in the spin loops.
- Stream line setting RIDs when they are better to be set via another
  function
- Add better support for setting home key via "ifconfig an0 wepkey 9:<key>"

Tested by:	Peter Radcliffe <pir@pir.net> (in -stable)
		myself in -current & -stable
MFC in:		3 days
