From e267e71e68aeeb51cbb9893ef9d61a59205826c4 Mon Sep 17 00:00:00 2001 From: Karthik D A Date: Mon, 21 Nov 2016 17:49:04 +0530 Subject: [PATCH] mwifiex: Disable adhoc feature based on firmware capability We will read fw_cap_info filled by firmware to check whether to skip ADHOC related commands or not. Also, IBSS_COALESCING_STATUS command has been moved from init path to adhoc network creation path.
