From 2e6a2d7b4508ea01b276d8c7350582a07dca1c23 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 31 Oct 2019 11:42:09 +0200 Subject: [PATCH] mlxsw: spectrum: Move max_width check up before count check The fact that the port cannot be split further should be checked before checking the count, so move it.
