From 7888fe53b7066c284e172d98d98d1865d6a9e5a0 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 16 Mar 2021 17:30:36 -0700 Subject: ethtool: Add common function for filling out strings Add a function to handle the common pattern of printing a string into the ethtool strings interface and incrementing the string pointer by the ETH_GSTRING_LEN. Most of the drivers end up doing this and several have implemented their own versions of this function so it would make sense to consolidate on one implementation.
