Subject: [PATCH 7/7] cfg80211: implement cfg80211_get_station cfg80211 API
Date: Mon, 14 Apr 2014 16:03:25 +0200 [thread overview]
Message-ID: <1397484205-20905-7-git-send-email-antonio@meshcoding.com> (raw)
In-Reply-To: <1397484205-20905-1-git-send-email-antonio@meshcoding.com>
From: Antonio Quartulli <antonio@open-mesh.com>
Implement and export the new cfg80211_get_station() API.
This utility can be used by other kernel modules to obtain
detailed information about a given wireless station.
It will be in particular useful to batman-adv which will
implement a wireless rate based metric.
