From 0064c5c1b3bf2a695c772c90e8dea38426a870ff Mon Sep 17 00:00:00 2001 From: Lev Stipakov Date: Fri, 13 Nov 2020 23:59:40 +0200 Subject: net: xfrm: use core API for updating/providing stats Commit d3fd65484c781 ("net: core: add dev_sw_netstats_tx_add") has added function "dev_sw_netstats_tx_add()" to update net device per-cpu TX stats. Use this function instead of own code. While on it, remove xfrmi_get_stats64() and replace it with dev_get_tstats64().
