  Log:
  Since resetting hardware takes a very long time and results in link
  renegotiation, we only initialize the hardware only when it is
  absolutely required. Process SIOCGIFADDR ioctl in em(4) when we know
  an IPv4 address is added. Handling SIOCGIFADDR in a driver is
  layering violation but it seems that there is no easy way without
  rewritting hardware initialization code to reduce settle time after
  reset.
  
  This should fix a long standing bug which didn't send ARP packet when
  interface address is changed or an alias address is added. Another
  effect of this fix is it doesn't need additional delays anymore when
  adding an alias address to the interface.
  While I'm here add a new if_flags into softc which remembers current
  prgroammed interface flags and make use of it when we have to program
  promiscuous mode.
