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.
