From ae7c03f68ee24e51f3ded9265715405df72812ba Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Fri, 18 Sep 2015 22:08:08 +0200 Subject: [PATCH] brcmfmac: Inform p2p module about p2pon through API When the p2pon module param is used then p2p attach will initialize p2p device iface in the firmware, but it is doing that by checking data. It is cleaner to pass the p2pon information to p2p by API. This information is also needed for other patch.
