Pyun YongHyeon 6ceb40baa9 Fix link state handling in bfe(4).
o conversion to callout(9) API.
 o add a missing driver lock in bfe_ifmedia_sts().
 o use our callout to drive watchdog timer.
 o restart Tx routine if pending queued packets are present in
   watchdog handler.
 o unarm watchdog timer only if there are no queued packets.
 o don't blindly reset phy and let phy driver handle link change
   request in bfe_init_locked().
 o return the status of mii_mediachg() to caller in
   bfe_ifmedia_upd(). Previously it always returned 0 to caller.
 o add check for IFF_DRV_RUNNING flag as well as IFF_DRV_OACTIVE
   in bfe_start_locked().
 o implement miibus_statchg method that keeps track of current
   link state changes as well as negotiated speed/duplex/
   flow-control configuration.
   Reprogram MAC to appropriate duplex state. Flow-control
   configuration was also implemented but commented out at the
   moment. The flow-control configuration will be enabled again
   after we have general flow-control framework in mii layer.
