From e89e2da29b7e2cba217a3e91a3106b708d0b878d Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Mon, 10 Sep 2012 18:30:45 -0700 Subject: [PATCH] mwifiex: use country ie of requested AP while associating AP's country ie is parsed and 11d information is updated in firmware while associating. Previous mwifiex_send_domain_info_cmd_fw() call in association path is not necessary now. Hence it is removed in this patch.
