From ee9219b2c268b228c0494c98259401e665457b87 Mon Sep 17 00:00:00 2001 From: Avraham Stern Date: Mon, 23 Mar 2015 15:09:27 +0200 Subject: iwlwifi: mvm: add UMAC scan iteration complete notification Add UMAC scan iteration complete notification. This notification can be enabled by setting scan_iter_notif_enabled through debugfs. Upon receiving this notification, print the list of channels that have been scanned in this iteration. This is useful for debugging.
