Subject: [RFC V3 3/5] cfg80211: add request id parameter to .sched_scan_stop() signature
Date: Wed, 15 Feb 2017 10:37:27 +0000 [thread overview]
Message-ID: <1487155049-1892-4-git-send-email-arend.vanspriel@broadcom.com> (raw)
In-Reply-To: <1487155049-1892-1-git-send-email-arend.vanspriel@broadcom.com>
For multiple scheduled scan support the driver needs to know which
scheduled scan request is being stopped. Pass the request id in the
.sched_scan_stop() callback.
