From 42760d95a0c192218b57f033ef39f7b493ffec59 Mon Sep 17 00:00:00 2001 From: Roi Dayan Date: Mon, 21 Nov 2022 12:14:50 +0200 Subject: [PATCH] net/mlx5e: Do early return when setup vports dests for slow path flow Adding flow flag cases in setup vport dests before the slow path case is incorrect as the slow path should take precedence. Current code doesn't show this importance so make the slow path case return early and separate from the other cases and remove the redundant comparison of it in the sample case.
