Subject: iwinfo: don't report AC capabilities on 2GHz-only interfaces
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fiwinfo.git;a=commitdiff_plain;h=40f2844fadc05f4a4de7699dbc12fee295b7057b

iwinfo: don't report AC capabilities on 2GHz-only interfaces

If a 802.11ac capable chip is in 2GHz-only mode, the hwmode
reported should be 802.11bgn.
