Subject: [PATCH] wpa_auth: Reconfigure group rekey timer upon wpa_reconfig
To: hostap@lists.infradead.org

During BSS reload (ctrl iface or SIGHUP) need to reconfigure the
group rekey timer, as it might change for specific BSS via the new config file.
If not reconfigured, the previous running timer will need to expire in order to apply
the new group rekey timeout.
