The dsa_port structure has a "netdev" member, which can be used for either the master device, or the slave device, depending on its type. It is true that today, CPU port are not exposed to userspace, thus the port's netdev member can be used to point to its master interface. But it is still slightly confusing, so split it into more explicit "master" and "slave" members inside an anonymous union.

The 88E6060 Ethernet switch always transmits the multicast bit of the switch MAC address as a zero. It re-uses the corresponding bit 8 of the register "Switch MAC Address Register Bytes 0 & 1" for "DiffAddr". If the "DiffAddr" bit is 0, then all ports transmit the same source address. If it is set to 1, then bit 2:0 are used for the port number. The mv88e6060 driver is currently wrongly shifting the MAC address byte 0 by 9. To fix this, shift it by 8 as usual and clear its bit 0.

An Ethernet switch may support having a MAC address, which can be used as the switch's source address in transmitted full-duplex Pause frames. If a DSA switch supports the related .set_addr operation, the DSA core sets the master's MAC address on the switch. This won't make sense anymore in a multi-CPU ports system, because there won't be a unique master device assigned to a switch tree. Instead, setup the switch from within the Marvell driver with a random MAC address, and remove the .set_addr implementation.

Turn on the out of band Advanced Congestion Buffering (ACB) mechanism at the switch level now that we have properly established the queue mapping between the switch egress queues and the SYSTEMPORT egress queues. This allows the switch to correctly backpressure the host system when one of its queue drops below the configured thresholds. This is also helping achieve so called "lossless" behavior by adapting the TX interrupt pacing to the actual speed and capacity of the switch port.

When both user ports are joined to the same bridge, the normal HW MAC learning is enabled. This means that unicast traffic is forwarded in HW. If one of the user ports leave the bridge, the ports goes back to the initial separated operation. Port separation relies on disabled HW MAC learning. Hence the condition that both ports must join same bridge. Add brigde methods port_bridge_join, port_bridge_leave and port_stp_state_set.

This reverts commit e85ec74a ("net: dsa: bcm_sf2: Defer port enabling to calling port_enable") because this now makes an unbind followed by a bind to fail connecting to the ingrated PHY. What this patch missed is that we need the PHY to be enabled with bcm_sf2_gphy_enable_set() before probing it on the MDIO bus. This is correctly done in the ops->setup() function, but by the time ops->port_enable() runs, this is too late. Upon unbind we would power down the PHY, and so when we would bind again, the PHY would be left powered off.
