Subject: [PATCH wireless-2.6 9/10] hostap: Filter disconnect events
Date: Sat, 12 Mar 2005 16:35:30 -0800 [thread overview]
Message-ID: <20050313003530.GJ8253@jm.kir.nu> (raw)
In-Reply-To: <20050313001706.GA8253@jm.kir.nu>
Filter out sequential disconnect events to make race condition with
received EAPOL frames less likely to happen (this improves
authentication success rate with some APs that send EAPOL frames very
quickly after the (re)association response).
