From b72611a2743c4198e3b031cf120e0bd432256c83 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Tue, 25 Sep 2018 10:34:30 +0800 Subject: [PATCH] net/i40e/base: read LLDP config area with correct endianness The NVM is in little endian so when we read from it we need to do the correct thing for the endianness of the machine.
