dsa: add DSA switch driver for Microchip KSZ9477 The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs. The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY.

net: dsa: modularize DSA_TAG_PROTO_NONE There is no reason that I can see why the no-op tagging protocol should be registered manually, so make it a module and make all drivers which have any sort of reference to DSA_TAG_PROTO_NONE select it. Note that I don't know if ksz_get_tag_protocol() really needs this, or if it's just the logic which is poorly written. All switches seem to have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a fallback that never gets used.

net: dsa: microchip: ptp: fix up PTP dependency When NET_DSA_MICROCHIP_KSZ_COMMON is built-in but PTP is a loadable module, the ksz_ptp support still causes a link failure: ld.lld-16: error: undefined symbol: ptp_clock_index >>> referenced by ksz_ptp.c >>> drivers/net/dsa/microchip/ksz_ptp.o:(ksz_get_ts_info) in archive vmlinux.a This can happen if NET_DSA_MICROCHIP_KSZ8863_SMI is enabled, or even if none of the KSZ9477_I2C/KSZ_SPI/KSZ8863_SMI ones are active but only the common module is. The most straightforward way to address this is to move the dependency to NET_DSA_MICROCHIP_KSZ_PTP itself, which can now only be enabled if both PTP_1588_CLOCK support is reachable from NET_DSA_MICROCHIP_KSZ_COMMON. Alternatively, one could make NET_DSA_MICROCHIP_KSZ_COMMON a hidden Kconfig symbol and extend the PTP_1588_CLOCK_OPTIONAL dependency to NET_DSA_MICROCHIP_KSZ8863_SMI as well, but that is a little more fragile.
