From 495083807f2007af7a29ea72768866f747021a98 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 13 Jul 2018 16:57:57 +0200 Subject: net: mscc: simplify retrieving the tag type from the frame header The tag type in the frame extraction header is only a bit wide. There's no need to use GENMASK when retrieving the information. This patch simplify the code by dropping GENMASK and using BIT instead.
