Subject: [RFC PATCH net-next 0/9] Get rid of the switchdev transactional model

This series comes after the late realization that the prepare/commit
separation imposed by switchdev does not help literally anybody:
https://patchwork.kernel.org/project/netdevbpf/patch/20201212203901.351331-1-vladimir.oltean@nxp.com/

We should kill it before it inflicts even more damage to the error
handling logic in drivers.

Vladimir Oltean (9):
  net: switchdev: remove the transaction structure from port object
    notifiers
  net: switchdev: delete switchdev_port_obj_add_now
  net: switchdev: remove the transaction structure from port attributes
  net: dsa: remove the transactional logic from ageing time notifiers
  net: dsa: remove the transactional logic from MDB entries
  net: dsa: remove the transactional logic from VLAN objects
  net: dsa: remove obsolete comment about switchdev transactions
  mlxsw: spectrum_switchdev: remove transactional logic for VLAN objects
  net: switchdev: delete the transaction object
