* iwlwifi: fix time interval misuse in iwl_poll_{direct_}bitZhu, Yi2008-12-12
| | | | | | | | | | | | The patch fixes the misuse of microsecond with millisecond in the polling mechanism of the iwlwifi driver. The impact of this problem is the unacceptable latency for the whole system (especially during bringing down the wlan interface).

* iwl3945: Fix rate scale for B-mode connectionAbbas, Mohamed2008-12-12
| | | | | | | | | | | | | | | | | This patch make sure we use only CCK rate for B only network. For 3945 driver, it sets REPLY_RATE_SCALE command every time we connect to a new network. In this command we set for every rate the number of try and next rate. The problem mac80211 reports same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause using invalid rate other than CCK in B only network. THis patch on association will examine sta valid rate on association, if no OFDM rate in valid available rates it considers it as B only mode so we can set REPLY_RATE_SCALE command with valid B only network and only choose CCK rate in rate scaling.

* iwlwifi: implement iwl_debug_report_frame for iwlagnHalperin, Daniel C2008-12-12
| | | | | | | | | | | The old version of this code was copied from 3945 and never updated. This patch cleans up structs that do not apply and accounts for other changes from 3945->iwlagn (e.g., PHY info can come in a separate cmd response from the ucode.)

* rtl8187: Improve wireless statistics for RTL8187Larry Finger2008-12-12
| | | | | | | | | | | | The current wireless statistics for the RTL8187 poorly indicate the signal strength and quality. With testing, I found that the AGC value is inversely correlated with the strength as in the RTL8187B. By implementing a similar calculation, much more code becomes common to the two devices.

* net: Add support for the KS8695 ethernet devices.Daniel Silverstone2008-12-12
| | | | | | | | | | | | | | | Implements the KS8695 ethernet device (ks8695net). This driver is only of use on the KS8695 which is an ARM9 based SoC. The documentation on this SoC is sparse and poor, with barely a register description and a rough outline of how the ethernet works, this driver was therefore written with strong reference to the Micrel supplied Linux 2.6.9 port, and to Andrew Victor's ks8695eth driver.

| | | | | | | | | | | | | | | | This is the last shoot of this series. After I removing all directly reference of netdev->priv, I am killing "priv" of "struct net_device" and fixing relative comments/docs. Anyone will not be allowed to reference netdev->priv directly. If you want to reference the memory of private data, use netdev_priv() instead. If the private data is not allocted when alloc_netdev(), use netdev->ml_priv to point that memory after you creating that private data.

* staging-p80211: Kill directly reference of netdev->privWang Chen2008-12-07
| | | | | | | | | | | | | | | | | In this driver, netdev's private data is wlandevice_t. And the wlandev(type of wlandevice_t) is exist before netdev be allocated. So use netdev->ml_priv to point to the private data. I am not sure whether I should consider the kernel version older than 2.3.38. Because in those kernels, netdevice_t is "structure dev" instead of "structure net_device" and of course "dev->ml_priv" will cause compile error. But before my patch, in function wlan_setup(), there is a ether_setup(net_device) which already broke kernels which older than 2.3.38.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under my 2.6.28-rc6 sparc64, when associating to an AP through my zd1211rw device, I was seeing kernel log messages like (not exact output): Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw] For the zd1211rw module, on RX, the 80211 packet will be located after the PLCP header in the skb data buffer. The PLCP header being 5 bytes long, the 80211 header will start unaligned from an aligned skb buffer. As per Documentation/unaligned-memory-access.txt, we must replace the not unaligned() safe compare_ether_addr() with memcmp() to protect architectures that require alignment.

| * ipw2200: fix netif_*_queue() removal regressionZhu Yi2008-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In "ipw2200: Call netif_*_queue() interfaces properly", netif_stop_queue() and netif_wake_queue() were removed with the reason "netif_carrier_{on,off}() handles starting and stopping packet flow into the driver". The patch also removes a valid condition check that ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state. But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't be called because linkwatch event is handled in a delayed workqueue. This caused a kernel oops reported by Frank Seidel: https://bugzilla.novell.com/show_bug.cgi?id=397390 This patch fixes the problem by moving the STATUS_ASSOCIATED check back to ipw_tx_skb(). It also adds a missing netif_carrier_off() call to ipw_disassociate().

Since the keys are not removed properly on suspend by mac80211 this may result in exhausting key table on resume leading to memory corruption during removal This patch also fixes a memory corruption problem reported in http://marc.info/?l=linux-wireless&m=122641417231586&w=2 and tracked in http://bugzilla.kernel.org/show_bug.cgi?id=12040. When the key is removed a second time the offset is set to 255 - this index is not valid for the ucode_key_table and corrupts the eeprom pointer (which is 255 bits from ucode_key_table).

Besides, just removing the controllers that where added on module load time and not those that were added later via b1isa_add_card() is wrong too - the place where all added cards are found is isa_dev[]. relevant dmesg lines: [ 0.000000] Linux version 2.6.27.4 (w@shubashi) (gcc version 4.3.2 (Debian 4.3.2-1) ) #3 Thu Oct 30 16:49:03 CET 2008 [ 67.403555] CAPI Subsystem Rev 1.1.2.8 [ 68.529154] capifs: Rev 1.1.2.3 [ 68.563292] capi20: Rev 1.1.2.7: started up with major 68 (middleware+capifs) [ 77.026936] b1: revision 1.1.2.2 [ 77.049992] b1isa: revision 1.1.2.3 [ 77.722655] kcapi: Controller [001]: b1isa-340 attached [ 77.722671] b1isa: AVM B1 ISA at i/o 0x340, irq 5, revision 255 [ 81.272669] b1isa-340: card 1 "B1" ready.

| * bnx2: Add workaround to handle missed MSI.Michael Chan2008-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI address/data are stored only when the MSI enable bit is toggled. As a result, SMP affinity no longer works in the latest kernel. A more serious problem is that the driver will no longer receive interrupts when the MSI receiving CPU goes offline. The workaround in this patch only addresses the problem of CPU going offline. When that happens, the driver's timer function will detect that it is making no forward progress on pending interrupt events and will recover from it. Eric Dumazet reported the problem. We also found that if an interrupt is internally asserted while MSI and INTA are disabled, the chip will end up in the same state after MSI is re-enabled. The same workaround is needed for this problem. Signed-off-by: Michael Chan <mchan@broadcom.com> Tested-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This makes the code in rt2x00queue more simpler and better concentrates all crypto code into a single location. With this we can also remove some ifdefs in rt2x00queue.c since the code inside the ifdef is either very small, or only calling empty functions (see empty function definitions in rt2x00lib.h).

| * | iwl3945 : Fix a-band association for passive channelsAbhijeet Kolekar2008-12-05

This enables sending of direct probes on passive channels, as long as some traffic is detected on that channel. This improves the scanning for hidden SSIDs in A-band,which is all passive channels. This patch fixes the bug no 1748. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748 2) This fix will only work with uCode version 15.28.2.8 and above. Prior versions of uCode would work only if we heard the traffic within active dwell time, which is much shorter than passive dwell time and is shorter than typical beacon periods. This patch also provids full active dwell time even if we hear traffic late in passive dwell. 3) uCode API version is incremented to 2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the infrastructure to support older firmware APIs. The API version number is stored as part of the filename, we first try to load the most recent firmware and progressively try lower versions. The API version is also read from the firmware self and stored as part of the iwl_priv structure. Only firmware that is supported by driver will be loaded. The version number read from firmware is compared to supported versions in the driver not the API version used as part of filename. An example using this new infrastrucure: if (IWL_UCODE_API(priv->ucode_ver) >= 2) { Driver interacts with Firmware API version >= 2. } else { Driver interacts with Firmware API version 1. } Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
