Subject: [PATCH wireless-2.6 8/10] hostap: Improved suspend
Date: Sat, 12 Mar 2005 16:34:48 -0800 [thread overview]
Message-ID: <20050313003448.GI8253@jm.kir.nu> (raw)
In-Reply-To: <20050313001706.GA8253@jm.kir.nu>
Improved suspend operation: disable firmware (hostap_cs) and
generate disconnect event to trigger wpa_supplicant to reassociate
immediately after resume.
