Subject: [net-next 06/15] net/mlx5: Bridge, pass net device when linking vport to bridge
From: Vlad Buslov <vladbu@...dia.com>
Following patch requires access to additional data in bridge net_device.
Pass the whole structure down the stack instead of adding necessary fields
as function arguments one-by-one.
