When a DSA driver offloads a bridge to firmware, it typically receives a
firmware-assigned bridge identifier (e.g. a FID) that must be stored and
retrieved by subsequent operations. Without a place to store this in the
DSA core's bridge structure, drivers must maintain a parallel list of
bridge objects and search it on every join, leave, and FDB operation.

Why list?

What's wrong with a driver-level array for lookup? The bridge.num is
guaranteed to be between 1 and ds->max_num_bridges.
