Commit Message

Vladimir Oltean Feb. 10, 2021, 9:14 a.m. UTC 
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 "mask" together into
a single switchdev attribute, and it also reduces some boilerplate in
the drivers that offload this.

Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com>
---
Changes in v3:
- Reworked mlxsw to check mask before performing any change.
- Also adapted the newly introduced dsa_port_change_brport_flags to the
  new API.

Changes in v2:
- Renamed "val" to "flags".
- Reworked drivers to check mask before performing any change.
