From 6a43cba3034015d1c029c8a81b62eb9c2660fd6e Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Mon, 6 Dec 2021 18:57:55 +0200 Subject: net: dsa: export bridging offload helpers to drivers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the static inline helpers from net/dsa/dsa_priv.h to include/net/dsa.h, so that drivers can call functions such as dsa_port_offloads_bridge_dev(), which will be necessary after the transition to a more complex bridge structure. More functions than are needed right now are being moved, but this is done for uniformity.
