2009-10-27libertas: remove unused 11d codeHolger Schurig1-3/+0
Most of the 11d code was protected with an "if (priv->enable11d)" clause. But there was no code that anywhere that was able to set this variable to true. So all 11d code was dead for almost a year and no one complained. That's enought incentive to remove this code. Besides removing old cruft, we gain back the 11d capability in a common way when we merge the cfg80211 functionality.

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.

2009-06-03libertas: improve function init/shutdown handling for SD8688Bing Zhao1-20/+0
This patch is to incorporate Dan Williams' comments for commit: "libertas: implement function init/shutdown commands for SD8688" 1. remove fn_init_required and fn_shutdown_required variables from lbs_private structure. If required, __lbs_cmd() will be called directly to send function init/shutdown command for SD8688 in if_sdio_probe() or if_sdio_remove() callback. 2. add global variable "user_rmmod" to distinguish between the module removal case and the card removal case. This flag will be checked in if_sdio_remove() against SD8688 card to determine whether or not the function shutdown command needs to be sent. 3. remove "card" from if_sdio_model structure as it cannot store card pointers for multiple cards. Besides, it's no longer needed to store the "card" pointer with changes #1 & #2 above. Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2009-05-22libertas: implement function init/shutdown commands for SD8688Bing Zhao1-0/+20
SD8688 is a WLAN/Bluetooth combo chip and both functions are supported in a single firmware image. FUNC_INIT and FUNC_SHUTDOWN commands are implemented to utilize the multiple function feature. When SD8688 card is inserted, the firmware image should be downloaded only once through either WLAN function (Libertas driver) or Bluetooth function (Bluetooth driver). This patch adds function init/shutdown for SD8688 WLAN function only. Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-26libertas: fix misuse of netdev_priv() and dev->ml_privKiran Divekar1-15/+16
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".

2008-11-10netdevice libertas: Fix directly reference of netdev->privWang Chen1-18/+18
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. Different to readonly reference of netdev->priv, in this driver, netdev->priv was changed. I use netdev->ml_priv to replace netdev->priv.

2008-06-09libertas: fix sleep confirmationHolger Schurig1-1/+1
This fixes an issus that made "iwconfig eth1 power on" non-working. When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().

2008-05-22libertas: fix multicast filtering on eth and msh interfacesDavid Woodhouse1-66/+101
We weren't properly handling multicast on the mesh interface. Fix that, which involves setting up the hardware to use the union of dev->mc_list for both eth%d and msh%d devices. This means we can't do it directly from ->set_multicast_list() because we'd need to lock the other device to read its list, and we can't do that because it might deadlock. So punt the actual work to keventd. Also, invoke the same when taking an interface down; for some reason the core calls ->set_multicast_list while IFF_UP is still set in dev->flags when we're taking it down, so its addresses don't get removed then. We also convert MAC_MULTICAST_ADR to a direct command while we're at it, removing one more entry from the big switch statement in the deprecated lbs_prepare_and_send_command() function.
