Message-Id: <1287720334-15469-1-git-send-email-harvey.harrison@gmail.com>
Date: Thu, 21 Oct 2010 21:05:32 -0700
From: Harvey Harrison <harvey.harrison@...il.com>

Cc: netdev@...r.kernel.org, shemminger@...tta.com
Subject: [PATCH 1/3] vmxnet3: remove set_flag_le{16,64} helpers
It's easier to just annotate the constants as little endian types and set/clear
the flags directly.
