From f46b9b8ee89b52f6ee1f4da49d392e609746ab10 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Thu, 7 Jan 2021 03:24:00 +0200 Subject: net: dsa: move the Broadcom tag information in a separate header file It is a bit strange to see something as specific as Broadcom SYSTEMPORT bits in the main DSA include file. Move these away into a separate header, and have the tagger and the SYSTEMPORT driver include them.
