Subject: [PATCH 3.13 041/140] mwifiex: fix wrong 11ac bits setting in fw_cap_info

3.13-stable review patch.  If anyone has any objections, please let me know.

From: Bing Zhao <bzhao@...vell.com>

commit 1e202242ee1432d68a8bea4919b2ae0ef19d9e06 upstream.

bit 14 is actually reserved and bit 12 & 13 should be used for
11ac capability in fw_cap_info.
