From 112f47373e364dd508cd9515f626b3fc83fddb10 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 8 May 2018 03:18:39 -0400 Subject: [PATCH] bnxt_en: Check unsupported speeds in bnxt_update_link() on PF only. [ Upstream commit dac0490718bd17df5e3995ffca14255e5f9ed22d ] Only non-NPAR PFs need to actively check and manage unsupported link speeds. NPAR functions and VFs do not control the link speed and should skip the unsupported speed detection logic, to avoid warning messages from firmware rejecting the unsupported firmware calls.
