Subject: [RFC net-next 00/13] Get rid of switchdev_ops

Hi all,

This patch series converts SWITCHDEV_PORT_ATTR_{GET,SET} to use a
blocking notifier, similar to how SWITCHDEV_PORT_OBJ_{ADD,DEL} has been
changed recently by Petr.

This was suggested by Ido to help with a particular use case I have
where I want to be able to veto a switchdev bridge attribute from a
driver (multicast_snooping).

Please review since I may not have gotten the driver abstraction right,
especially for mlx5e and nfp since these are *hum* *hum* large drivers.
