From dd5382a08157756510aa8d7269c662eccde775cb Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 7 Nov 2019 16:27:15 -0800 Subject: net: provide dev_lstats_add() helper Many network drivers need it and hand-coded the same function. In order to ease u64_stats_t adoption, it is time to factorize. Signed-off-by: Eric Dumazet Signed-off-by: David S.
