From: Vladimir Oltean <vladimir.oltean@nxp.com>

There does not appear to be any strong reason why
br_switchdev_set_port_flag issues a separate notification for checking
the supported brport flags rather than just attempting to apply them and
propagating the error if that fails.

However, there is a reason why this switchdev API is counterproductive
for a driver writer, and that is because although br_switchdev_set_port_flag
gets passed a "flags" and a "mask", those are passed piecemeal to the
driver, so while the PRE_BRIDGE_FLAGS listener knows what changed
because it has the "mask", the BRIDGE_FLAGS listener doesn't, because it
only has the final value. This means that "edge detection" needs to be
done by each individual BRIDGE_FLAGS listener by XOR-ing the old and the
new flags, which in turn means that copying the flags into a driver
private variable is strictly necessary.

This can be solved by passing the "flags" and the "value" together into
a single switchdev attribute, and it also reduces some boilerplate in
the drivers that offload this.

Could you also check the mask to see if the flag needs to be actually changed?

In the previous patch you add the .port_pre_bridge_flags()
dsa_switch_ops only to remove it here. Couldn't these two patches be in
reverse order so that there is no need to actually add the callback in
the first place?
