[RFC net-next mlxsw v8 0/2] mlxsw: lib: Manager for priority base pruning lookups

[Tal Bar]

An object (e.g. packet) needs to be evaluated against a data base of
prune items (represented by {key, mask, priority}) contained in the prune 
object, so that the matching item with the highest priority is selected to
continue process the object. This patchset is addressing that problem, by
reducing the number of lookups between different tables prune object.

The first patch introducing this capability.
