This commit adds support for the GENETv5 implementation. The GENETv5 reports a major version of 6 instead of 5 so compensate for this when verifying the configuration of the driver. Also the EPHY revision is now contained in the MDIO registers of the PHY so the EPHY revision of 0 in GENET_VER_FMT is expected for GENETv5.

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.

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.

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.

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.

This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].

Support prepending data from XDP. We are already always allocating some headroom because FW may prepend metadata to packets. xdp_adjust_head() can be supported by making sure that headroom is big enough for XDP.

Instead of passing around sets of rings and their parameters just store all information in the data path structure. We will no longer user xchg() on XDP programs when we swap programs while the traffic is guaranteed not to be flowing. This allows us to simply assign the entire data path structures instead of copying field by field. The optimization to reallocate only the rings on the side (RX/TX) which has been changed is also removed since it seems like it's not worth the code complexity.
