  Log:
  SVN rev 213696 on 2010-10-11 19:20:53Z by yongari
  
  Do not setup interrupt endpoint for axe(4).
  It seems axe(4) controllers support interrupt endpoint such that
  enabling interrupt endpoint generates about 1000 interrupts/sec.
  Controllers transfer 8 bytes data through interrupt endpoint and
  the data include link UP/DOWN state as well as some PHY related
  information. Previously axe(4) didn't use the transferred data and
  didn't even try to read the data. Because axe(4) counts on mii(4)
  to detect link state changes there is no need to use interrupt
  endpoint here.
  
  This change fixes generation of unnecessary interrupts which was
  seen when interface is brought to UP.
  
  No objections from:     hselasky
