Subject: tests: Add test that fails the MLD association after hostapd success
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ff1a7af0963b31efecda1999118f0a90ad6b842;p=thirdparty%2Fhostap.git

tests: Add test that fails the MLD association after hostapd success

This test checks the flow where an error happens on the first
association attempt but everything looks fine from the perspective of
the AP. In this case, the AP will receive a second authentication even
though it thinks the client is already associated.
