From 2ae0bf501425cbddc8b992a2b65fc04d911cae8c Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Mon, 12 Dec 2016 15:44:14 -0800 Subject: [PATCH] i40e: convert to cpu from le16 to generate switch_id correctly On Big Endian platforms we would incorrectly calculate the wrong switch id since we did not properly convert the le16 value into CPU format. Caught by sparse.
