Subject: [patch net-next 2/7] mlxsw: core: Convert fwd_entry_ref list to be generic per-block resource list
From: Jiri Pirko <jiri@...lanox.com>
Since the resource list needs to be used also for other entries different
to fwd_entry_ref, make the list generic. For that purpose, introduce a
resource structure with couple of helpers that the code which need to
store a per-block resource should use.
