From: Andre Heider Date: Tue, 22 Nov 2022 10:35:41 +0000 (+0100) Subject: iwinfo: reuse infos provided by libiwinfo X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c46ad61d49de411fc5bc64dd0bdd48518601487b;p=project%2Frpcd.git iwinfo: reuse infos provided by libiwinfo Don't hardcode bit/name pairs, instead iterate over what's known to the library and use that instead. This automatically adds the missing ciphers CCMP256 and GCMP256 - and any future ones. The only difference in the output is the order of the 'hwmodes' array.
