Subject: [PATCH 03/21] rt2x00: Limit beacon updates in bss_info_changed to USB devices
Date: Sun, 30 Jan 2011 13:16:52 +0100 [thread overview]
Message-ID: <201101301316.53532.IvDoorn@gmail.com> (raw)
In-Reply-To: <201101301316.29086.IvDoorn@gmail.com>
From: Helmut Schaa <helmut.schaa@googlemail.com>
Currently there are two places that trigger a beacon update on PCI
devices. The bss_info_changed callback and the periodic update
triggered by the TBTT or PRETBTT interrupt.
Since the next TBTT or PRETBTT interrupt will periodically fetch an
updated beacon remove the update_beacon call in the bss_info_changed
callback for PCI devices.
In the worst case it will take one beacon interval longer to fetch
the new beacon then before. For devices that have a PRETBTT interrupt
there should be no change at all.
