Subject: broadcom-wl: fix band reporting
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=40e8eb2dda9ada0133e020d2c47bd8b8e02645df;p=openwrt%2Fstaging%2Fthess.git

broadcom-wl: fix band reporting

Modify the band reporting for broadcom devices to correctly report
HW capability.  Currently, 802.11na devices report "bgn"; but should be
reporting "an".
