Subject: iwinfo: Add support for WPA3
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f8ef45065207b93b6a1df2a6619e82fef121f8bb;p=project%2Fiwinfo.git

iwinfo: Add support for WPA3

This patch adds support for WPA3, meaning SAE and OWE are now properly identified.
This fixes iwinfo and LuCi showing WPA2 NONE for WPA3 SAE and OWE.
