From 5e4cb4800168671c7d599416ded360bac6c4b319 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 29 Oct 2020 18:33:46 +0100 Subject: [PATCH] r8169: use struct pcpu_sw_netstats for rx/tx packet/byte counters Switch to the net core rx/tx byte/packet counter infrastructure. This simplifies the code, only small drawback is some memory overhead because we use just one queue, but allocate the counters per cpu.
