Detailed Description

Wi-Fi Direct - P2P Group Owner Negotiation.

Function Documentation

void p2p_reselect_channel	(	struct p2p_data *	p2p,
		struct p2p_channels *	intersection
	)

Re-select operating channel based on peer information.

Parameters

p2p	P2P module context from p2p_init()
intersection	Support channel list intersection from local and peer

This function is used to re-select the best channel after having received information from the peer to allow supported channel lists to be intersected. This can be used to improve initial channel selection done in p2p_prepare_channel() prior to the start of GO Negotiation. In addition, this can be used for Invitation case.
