Subject: [PATCH v2 3/3] mwifiex: selectively choose ext_scan support
Date: Fri, 23 Jan 2015 17:09:19 +0530	[thread overview]
Message-ID: <1422013159-3093-3-git-send-email-patila@marvell.com> (raw)
In-Reply-To: <1422013159-3093-1-git-send-email-patila@marvell.com>

Some devices do not support extended scan.
This patch adds support to enble ext_scan selectively.
For SD/PCIe interfaces, deefine ext_scan_support as part of
card structure and use it to initialize ext_scan in adapter
during registering device. For USB interfaces, we initialize
ext_scan during register_dev handler.
