From a85b32ebaac08970d41a7b0105ce51fed90d153e 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.
