Subject: Add sae_rejected_groups to hostapd STA control interface command
X-Git-Tag: hostap_2_10~2166
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7fde39fb1a9e110e273971a613d2375cec350afb;p=thirdparty%2Fhostap.git

Add sae_rejected_groups to hostapd STA control interface command

This is mainly for testing purposes to be able to check which groups
a STA reports as having been rejected when using SAE H2E.
