[PATCH net-next v8 1/4] net: dsa: move dsa_bridge_ports() helper to dsa.h

From: Daniel Golle

Date: Thu Mar 26 2026 - 21:00:56 EST


The yt921x driver contains a helper to create a bitmap of ports
which are members of a bridge.

Move the helper as static inline function into dsa.h, so other driver
can make use of it as well.
