From 7b82c4de0d67719390674215d4580e20459f5b9b Mon Sep 17 00:00:00 2001 From: Kalesh AP Date: Thu, 20 Jan 2022 14:42:25 +0530 Subject: [PATCH] net/bnxt: fix check for autoneg enablement HWRM_PORT_PHY_QCFG_OUTPUT response indicates the autoneg speed mask supported by the FW. While enabling autoneg, driver should also check the FW advertised PAM4 speeds supported in auto mode which is set in the HWRM_PORT_PHY_QCFG_OUTPUT response.
