2009-10-07libertas: Add auto deep sleep support for SD8385/SD8686/SD8688Amitkumar Karwar
Add timer based auto deep sleep feature in libertas driver which can be configured using iwconfig command. This is tested on SD8688, SD8686 cards with firmware versions 10.38.1.p25, 9.70.4.p0 respectively on 32-bit and 64-bit platforms. Tests have been done for USB/CS cards to make sure that the patch won't break USB/CS code. We didn't test the if_spi driver.

2009-07-10libertas: remove ps_supported flag, use fwcapinfoAndrey Yurovsky
Power save support depends on the firmware capabilities rather than the card's hardware interface. Use the FW_CAPINFO_PS bit in the firmware capabilities mask throughout the driver in place of the redundant ps_supported flag and don't make decisions about PS support in the interface drivers (with the exception of a special case in the USB driver). V2: put the USB special case in the right place. Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-26libertas: fix misuse of netdev_priv() and dev->ml_privKiran Divekar
The mesh and radiotap interfaces need to use the same private data as the main wifi interface. If the main wifi interface uses netdev_priv(), but the other interfaces ->ml_priv, there's no way to figure out where the private data actually is in the WEXT handlers and netdevice callbacks. So make everything use ->ml_priv. Fixes botched netdev_priv() conversion introduced by "netdevice libertas: Fix directly reference of netdev->priv", though admittedly libertas' use of ->priv was somewhat "special".

2008-11-21libertas: Fine grained configuration of wake-on-lan.Anna Neal
Based on a patch from Shailendra Govardhan <shailen@marvell.com>. This patch allows implementation of more specific wake-on-lan rules than those of ethtool. Please note that only firmware 5.110.22.p20 and above supports this feature. This patch only implements the driver/firmware interface, not the userspace/driver interface.

2008-09-15libertas: remove unused generic RESET commandDan Williams
The generic reset command is unused. Each interface type needs to handle the reset command differently since after reset, the firmware is dead and interface-specific mechanisms must be used to reinitialize the card.

2008-04-16libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig
This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.
