From 587652bbdd06ab38a4c1b85e40f933d2cf4a1147 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 15 Nov 2021 09:05:54 -0800 Subject: net: gro: populate net/core/gro.c Move gro code and data from net/core/dev.c to net/core/gro.c to ease maintenance. gro_normal_list() and gro_normal_one() are inlined because they are called from both files.
