From f3e2778429c2ad8555e888858e0f0e98c86c4b0f Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Thu, 14 Dec 2017 12:34:46 +0300 Subject: net: aquantia: Update hw counters on hw init On very first start we should read out current HW counter values to make diff based calculations later. This also should be done each time NIC gets down/up or wakes up after sleep state. We reset link state explicitly to prevent diffs from being summed this first time.
