From f88439918589332a2c5feef225b9644873cd0769 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 16 Mar 2021 13:24:11 +0200 Subject: [PATCH] Documentation: networking: dsa: remove references to switchdev prepare/commit After the recent series containing commit bae33f2b5afe ("net: switchdev: remove the transaction structure from port attributes"), there aren't prepare/commit transactional phases anymore in most of the switchdev objects/attributes, and as a result, there aren't any in the DSA driver API either. So remove this piece. Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S.
