From aa620993b1e58e19a556bc3a7f0e15ac08bf2e46 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Tue, 30 Mar 2021 12:52:10 -0700 Subject: [PATCH] ionic: pull per-q stats work out of queue loops Abstract out the per-queue data collection work into separate functions from the per-queue loops in the stats reporting, similar to what Alex did for the data label strings in commit acebe5b6107c ("ionic: Update driver to use ethtool_sprintf") Signed-off-by: Shannon Nelson Signed-off-by: David S.
