Subject: AP MLD: Fix SA query timeout during MLD reassociation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=80843bff3e3baddaf3e6486b8d72b48865f5eec1;p=thirdparty%2Fhostap.git

AP MLD: Fix SA query timeout during MLD reassociation

If an AP MLD receives a (Re)Association Request frame from an associated
non-AP MLD and if SA query has already timed out for the existing
station entry, the link address should be updated since the non-AP MLD
might have changed its link address in the new association.
