Subject: [net-next 03/17] net/mlx5e: Pass attr arg for attaching/detaching encaps
From: Roi Dayan <roid@...dia.com>
In later commit that we will have multiple attr instances per flow
we would like to pass a specific attr instance to set encaps.
Currently the mlx5_flow object contains a single mlx5_attr instance.
However, multi table actions (e.g. CT) instantiate multiple attr instances.
Currently mlx5e_attach/detach_encap() reads the first attr instance
from the flow instance. Modify the functions to receive the attr
instance as a parameter which is set by the calling function.
