From bef3c6c9374da40ec63698cd504474366a9de2ff Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 5 Feb 2016 15:27:31 -0800 Subject: net: Drop unecessary enc_features variable from tunnel segmentation functions The enc_features variable isn't necessary since features isn't used anywhere after we create enc_features so instead just use a destructive AND on features itself and save ourselves the variable declaration.
