From e2f08207c558bc0bc8abaa557cdb29bad776ac7b Mon Sep 17 00:00:00 2001 From: Moshe Tal Date: Thu, 20 Jan 2022 11:55:50 +0200 Subject: [PATCH] ethtool: Fix link extended state for big endian The link extended sub-states are assigned as enum that is an integer size but read from a union as u8, this is working for small values on little endian systems but for big endian this always give 0. Fix the variable in the union to match the enum size.
