Subject: [PATCH v2 net-next 00/11] Cleanup in brport flags switchdev offload for DSA

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

The initial goal of this series was to have better support for
standalone ports mode and multiple bridges on the DSA drivers like
ocelot/felix and sja1105. Proper support for standalone mode requires
disabling address learning, which in turn requires interaction with the
switchdev notifier, which is actually where most of the patches are.

I also noticed that most of the drivers are actually talking either to
firmware or SPI/MDIO connected devices from the brport flags switchdev
attribute handler, so it makes sense to actually make it sleepable
instead of atomic.

Vladimir Oltean (11):
  net: switchdev: propagate extack to port attributes
  net: bridge: offload all port flags at once in br_setport
  net: bridge: don't print in br_switchdev_set_port_flag
  net: bridge: offload initial and final port flags through switchdev
  net: dsa: stop setting initial and final brport flags
  net: squash switchdev attributes PRE_BRIDGE_FLAGS and BRIDGE_FLAGS
  net: dsa: kill .port_egress_floods overengineering
  net: bridge: put SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS on the blocking
    call chain
  net: mscc: ocelot: use separate flooding PGID for broadcast
  net: mscc: ocelot: offload bridge port flags to device
  net: dsa: sja1105: offload bridge port flags to device
