2017-03-13net: bcmgenet: return EOPNOTSUPP for unknown ioctl commandsDoug Berger
This commit changes the ioctl handling behavior to return the EOPNOTSUPP error code instead of the EINVAL error code when an unknown ioctl command value is detected. It also removes some redundant parsing of the ioctl command value and allows the SIOCSHWTSTAMP value to be handled.

2017-03-13net: bcmgenet: correct return value of __bcmgenet_tx_reclaimDoug Berger
The reclaim function should return the number of buffer descriptors reclaimed, not just the number corresponding to skb packets. Also, remove the unnecessary computation when updating the consumer index. While this is not a functional problem it could degrade performance of napi in a fragmented transmit stream.

2017-03-13net: bcmgenet: clear status to reduce spurious interruptsDoug Berger
Since the DMA interrupt status is latched and the DMA servicing can be polled, it is a good idea to clear the latched status of a DMA interrupt before performing the service that would be invoked by the interrupt. This prevents old status from causing spurious interrupts when the interrupt is unmasked at a later time.

2017-03-13net: bcmgenet: remove handling of wol interrupts from isr0Doug Berger
The bcmgenet_wol_isr() handler performs the necessary processing for waking from a GENET event. There is no necessary functionality behind servicing the UMAC_IRQ_MPD_R event in the handling of isr0. Therefore the code that unmasks and masks this interrupt and that gets invoked in response to it is removed by this commit.

2017-03-09net: bcmgenet: Power up the internal PHY before probing the MIIDoug Berger
When using the internal PHY it must be powered up when the MII is probed or the PHY will not be detected. Since the PHY is powered up at reset this has not been a problem. However, when the kernel is restarted with kexec the PHY will likely be powered down when the kernel starts so it will not be detected and the Ethernet link will not be established. This commit explicitly powers up the internal PHY when the GENET driver is probed to correct this behavior.
