Subject: [PATCH net-next 03/15] bridge: switchdev: Reflect MAB bridge port flag to device drivers

From: Ido Schimmel <idosch@...dia.com>

Reflect the 'BR_PORT_MAB' flag to device drivers so that:

* Drivers that support MAB could act upon the flag being toggled.
* Drivers that do not support MAB will prevent MAB from being enabled.
