New Revision: 241393

Log:
  Remove unnecessary delay. I don't see any comments in data sheet
  that requires 10ms delay after device reset.  Because that code was
  there from day 1, I guess it was added to give enough settlement
  time after updating BGE_MAC_MODE register.
  The recommended delay time for BGE_MAC_MODE after updating is 40us
  and it was already done in r241219.
