From 4875e0b5208555a9cc2c45558f016e0814cbd6cb Mon Sep 17 00:00:00 2001 From: Erik Stromdahl Date: Tue, 4 Sep 2018 15:05:04 +0300 Subject: [PATCH] ath10k: add per target config of max_num_peers This patch makes sure the value of max_num_peers matches num_peers in hw_params (if set to a non zero value). hw_params->num_peers is used in the TLV WMI init command. If ar->max_num_peers is not set to the same value, there is a risk that the user creates more peers than the maximum number of peers supported by the device.
