From d3a90b70d8ffe6dd82a3fa22515a2ebc399aca28 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Wed, 16 Apr 2014 01:21:40 +0000 Subject: [PATCH] i40e: don't use OR to check a value A couple of FD checks ended up using bitwise OR to check a value, which ends up always being evaluated to true. This should fix the issue. Thanks to DaveJ for noticing and reporting the issue!
