Subject: [PATCH net-next 13/15] mlxsw: spectrum_router: Introduce fib_entry priv for low-level ops
From: Jiri Pirko <jiri@...dia.com>
Prepare for the low-level ops that need to store some data alongside
the fib_entry and introduce a per-fib_entry priv for ll ops.
The priv is reference counted as in the follow-up patch it is going
to be saved in pack() function and used later on in commit() even in
case the related fib_entry gets freed in the middle.
