From: Vladimir Oltean Date: Mon, 21 Nov 2022 13:55:41 +0000 (+0200) Subject: net: dsa: move bulk of devlink code to devlink.{c,h} X-Git-Tag: v6.6.7~3913^2~142^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5cf2c75b5b91bcf81d61b2d2ea1c71363bcacf89;p=platform%2Fkernel%2Flinux-starfive.git net: dsa: move bulk of devlink code to devlink.{c,h} dsa.c and dsa2.c are bloated with too much off-topic code. Identify all code related to devlink and move it to a new devlink.c file. Steer clear of the dsa_priv.h dumping ground antipattern and create a dedicated devlink.h for it, which will be included only by the C files which need it. Usage of dsa_priv.h will be minimized in later patches.
