[PATCH net-next v3 6/6] net: dsa: bcm_sf2: Register our slave MDIO bus

Register a slave MDIO bus which allows us to divert problematic read/writes towards conflicting pseudo-PHY address (30). Do no longer rely on DSA's slave_mii_bus, but instead provide our own implementation which offers more flexibility as to what to do, and when to register it. We need to

[PATCH net-next v3 5/6] net: dsa: Initialize CPU port ethtool ops per tree

Now that we can properly support multiple distinct trees in the system, using a global variable: dsa_cpu_port_ethtool_ops is getting clobbered as soon as the second switch tree gets probed, and we don't want that. We need to move this to be dynamically allocated, and since we can't really be

[PATCH net-next v3 0/6] net: dsa: misc improvements

Hi all, This patch series builds on top of Andrew's "New DSA bind, switches as devices" patch set and does the following: - add a few helper functions/goodies for net/dsa/dsa2.c to be as close as possible from net/dsa/dsa.c in terms of what drivers can expect, in particular the slave MDIO

[PATCH net-next v3 1/6] net: dsa: Provide unique DSA slave MII bus names
