From ef936a36b0f17fef9a2aa48a1107f07db0de5813 Mon Sep 17 00:00:00 2001 From: Zhang Shengju Date: Thu, 3 Mar 2016 01:16:57 +0000 Subject: [PATCH] wireless: use reset to set mac header Since offset is zero, it's not necessary to use set function. Reset function is straightforward, and will remove the unnecessary add operation in set function. Signed-off-by: Zhang Shengju Signed-off-by: David S.
