From acebe5b6107c73aade7f3beca441329ff04823a3 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 16 Mar 2021 17:31:55 -0700 Subject: [PATCH] ionic: Update driver to use ethtool_sprintf Update the ionic driver to make use of ethtool_sprintf. In addition add separate functions for Tx/Rx stats strings in order to reduce the total amount of indenting needed in the driver code.
