From cb0ef1d1dc8739e307f70493b7eb1184685dbbde Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 6 Feb 2017 18:26:26 -0800 Subject: [PATCH] igb: Only sync size of expected frame in ethtool testing We only need to sync the size of the frame that is read to test. We don't need to sync the entire Rx buffer. This way the testing is more consistent with how we handle things in the receive path.
