Subject: [net-next 2/4] mac80211_hwsim: use reset to set mac header
Date: Tue, 1 Mar 2016 09:27:36 +0000 [thread overview]
Message-ID: <1456824458-19499-3-git-send-email-zhangshengju@cmss.chinamobile.com> (raw)
In-Reply-To: <1456824458-19499-1-git-send-email-zhangshengju@cmss.chinamobile.com>
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.
