Subject: [PATCH V2 net-next] net: marvell: prestera: implement br_port_locked flag offloading
Both <port> br_port_locked and <lag> interfaces's flag
offloading is supported. No new ABI is being added,
rather existing (port_param_set) API call gets extended.
Signed-off-by: Oleksandr Mazur <oleksandr.mazur@...ision.eu>
V2:
add missing receipents (linux-kernel, netdev)
