All drivers that select MII also need to select NET_CORE because MII depends on it. This is a bit ridiculous because NET_CORE is just a menu option that doesn't enable any code by itself. There is also no need for it to be a visible option, since its users all select it.

Older Single Queue (SQ_SG_MODE) devices like TSEC (i.e. mpc83xx) don't feature the frame receive indication bits (RXF) in RSTAT. For these and for the rest of the SQ_SG_MODE devices, provide the appropiate polling routine that handles a single pair of Rx/Tx BD rings, removing the overhead incurred by the multiple queues/ multiple interrupt group devices (veTSEC/ eTSEC2.0 devices). So this is primarily a fix for the TSEC devices. Signed-off-by: NClaudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

commit 54309fa6 ("net: fec: fix kernel oops when plug/unplug cable many times") introduced the following 'if' block in the beginning of fec_start(): if (netif_running(ndev)) { netif_device_detach(ndev); napi_disable(&fep->napi); netif_stop_queue(ndev); netif_tx_lock_bh(ndev); } Then later in the end of fec_restart() there is another block that calls the opposite of each one of these functions. The correct approach would be to also call them with in the reverse order, so that we have as result: if (netif_running(ndev)) { netif_tx_unlock_bh(ndev); netif_wake_queue(ndev); napi_enable(&fep->napi); netif_device_attach(ndev); } Suggested-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NFabio Estevam <fabio.estevam@freescale.com> Signed-off-by: NDavid S.

Similar, since of_get_phy_mode() is now defined as dummy function if OF_NET is not configured, it is no longer necessary to provide an OF dependent function as front-end. Also, the function depends on OF_NET, not on OF, so the conditional code was not correct anyway. Drop the front-end function and call of_get_phy_mode() directly.
