[PATCH] P2P: Added Go Intent of connecting device in GO Negotiation Request event
MAYANK HAARIT
mayank.h
Mon Jun 1 22:47:33 PDT 2015
This patch is to add GO Intent information of connecting device in GO
Negotiation Request event which will help applications to decide it's
own go intent value in advance and can avoid fail case when both
devices sends go_intent=15 depending on application requirement.
