Subject: [PATCH wpan-next 04/12] mac802154: introduce IEEE802154_DEV_TO_SUB_IF
Date: Wed, 13 Aug 2014 15:46:27 +0200	[thread overview]
Message-ID: <1407937595-16415-5-git-send-email-alex.aring@gmail.com> (raw)
In-Reply-To: <1407937595-16415-1-git-send-email-alex.aring@gmail.com>

This function adds a wrapper to call netdev_priv to getting the sdata
attribute. There exists a similar function in the wirless stack.
