* rfkill: preserve state across suspendHenrique de Moraes Holschuh2008-11-262-1/+7
| | | | | | | | | | | | | | | | | | | | The rfkill class API requires that the driver connected to a class call rfkill_force_state() on resume to update the real state of the rfkill controller, OR that it provides a get_state() hook. This means there is potentially a hidden call in the resume code flow that changes rfkill->state (i.e. rfkill_force_state()), so the previous state of the transmitter was being lost. The simplest and most future-proof way to fix this is to explicitly store the pre-sleep state on the rfkill structure, and restore from that on resume.

* mac80211: Look out for some other AP when disassoc is received.Vivek Natarajan2008-11-261-2/+6
| | | | | | | | | | | When a disassoc packet is received from the AP with a reason code of 'leaving the BSS', mac80211 should go into DISABLED state just as it would do if the AP suddenly went away for some reason, as that is what will happen shortly after the AP leaves anyway.

* ath9k: make DMA memory consistentLuis R. Rodriguez2008-11-251-2/+11
| | | | | | | | | | | | | Make the DMAable mameory consistent with pci_set_consistent_dma_mask(). The DMA-mapping.txt Documentation recommends this but for PCI-X considerations and on strange architecture like SGI SN2, not sure why it would fix an issue but lets see if it does, just in case. Before this, this driver was tested with x86_64 with about 7 GB of RAM, not sure if this is really needed. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

| | | | | | | | | Use DMA_32BIT_MASK to clarify we only want 32-bit DMA memory. What was there before is also 32-bit but this makes it clearer Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Detect USB BULK in/out endpointsIvo van Doorn2008-11-255-28/+111
| | | | | | | | | | | | | | | | | | | | | | Instead of hardcoding the used in/out endpoints we should detect them by walking through all available endpoints. rt2800usb will gain the most out of this, because the legacy drivers indicate that there are multiple endpoints available. However this code might benefit at least rt73usb as well for the MIMO queues, and if we are really lucky rt2500usb will benefit because for the TX and PRIO queues. Even if rt2500usb and rt73usb do not get better performance after this patch, the endpoint detection still belongs to rt2x00usb, and it shouldn't hurt to always try to detect the available endpoints.

* rtl8187: Remove module warning and dependence on CONFIG_EXPERIMENTALLarry Finger2008-11-252-4/+2
| | | | | | | | | | | | After considerable testing, the initial fears that the driver might damage some flavors of RTL8187B hardware seem to be groundless. Accordingly, the logged warning is removed. In addition, Kconfig is changed to remove the dependence on EXPERIMENTAL.

* rtl8187: feedback transmitted packets using tx close descriptor for 8187BHerton Ronaldo Krzesinski2008-11-252-4/+136
| | | | | | | | | | | | | | Realtek 8187B has a receive command queue to feedback beacon interrupt and transmitted packet status. Use it to feedback mac80211 about status of transmitted packets. Unfortunately in the course of testing I found that the sequence number reported by hardware includes entire sequence control in a 12 bit only field, so a workaround is done to check only lowest bits.

* rtl8187: fix 8187B throughput regressionHerton Ronaldo Krzesinski2008-11-251-1/+1
| | | | | | | | | | | | | Hin-Tak Leung reported that after the change "rtl8187: add short slot handling for 8187B" his RTL8187B started to give low throughput on network transfers. Turns out that the SIFS setting used isn't ok, it doesn't look to be the real aSIFSTime, using the "magical" 0x22 value like on other 818x variants as the vendor does too fixes the issue.
