Message-Id: <1456824458-19499-3-git-send-email-zhangshengju@cmss.chinamobile.com> Date: Tue, 1 Mar 2016 09:27:36 +0000 From: Zhang Shengju <zhangshengju@...s.chinamobile.com> To: davem@...emloft.net, kvalo@...eaurora.org, johannes@...solutions.net, netdev@...r.kernel.org Subject: [net-next 2/4] mac80211_hwsim: use reset to set mac header Since offset is zeor, it's not necessary to use set function. Reset function is straightforward, and will remove the unnecessary add operation in set function.
