From a75519a84855bca029ce7d8a27de9409d9b84956 Mon Sep 17 00:00:00 2001 From: Tom Seewald Date: Sun, 21 Feb 2021 22:00:05 -0600 Subject: [PATCH] igb: Fix duplicate include guard The include guard "_E1000_HW_H_" is used by two separate header files in two different drivers (e1000/e1000_hw.h and igb/e1000_hw.h). Using the same include guard macro in more than one header file may cause unexpected behavior from the compiler. Fix this by renaming the duplicate guard in the igb driver.
