Display sw_in_discards, sw_in_filtered, and sw_out_filtered for chips supported by mv88e6123_61_65 and mv88e6352 drivers. The variables are provided in port registers, not the normal status registers. Mark by adding 0x100 to the register offset and add special handling code to mv88e6xxx_get_ethtool_stats.

Commit b4d2394d ("dsa: Replace mii_bus with a generic host device") replaces mii_bus with a generic host_dev, and introduces dsa_host_dev_to_mii_bus() to support conversion from host_dev to mii_bus. However, in some cases it uses to_mii_bus to perform that conversion. Since host_dev is not the phy bus device but typically a platform device, this fails and results in a crash with the affected drivers.

This change makes it so that instead of passing and storing a mii_bus we instead pass and store a host_dev. From there we can test to determine the exact type of device, and can verify it is the correct device for our switch. So for example it would be possible to pass a device pointer from a pci_dev and instead of checking for a PHY ID we could check for a vendor and/or device ID.

Add support for the Marvell 88E6131 switch chip. This chip only supports the original (ethertype-less) DSA tagging format. On the 88E6131, there is a PHY Polling Unit (PPU) which has exclusive access to each of the PHYs's MII management registers. If we want to talk to the PHYs from software, we have to disable the PPU and wait for it to complete its current transaction before we can do so, and we need to re-enable the PPU afterwards to make sure that the switch will notice changes in link state and speed on the individual ports as they occur. Since disabling the PPU is rather slow, and since MII management accesses are typically done in bursts, this patch keeps the PPU disabled for 10ms after a software access completes. This makes handling the PPU slightly more complex, but speeds up something like running ethtool on one of the switch slave interfaces from ~300ms to ~30ms on typical hardware.

Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)
