2009-04-22ar9170: support HT receive and channel configJohannes Berg
This patch adds support for configuring HT40 channels and receiving HT40 to ar9170. Receiving aggregation doesn't seem to work right now, so it's not enabled. Same goes for TX aggregation, but that probably needs even more work. With this, I can receive roughly 33 Mbits/sec. The HT capabilities are a little odd, I tried following otus here -- in particular having SGI_40 but not SGI_20 is a little weird but afaict that's what otus does.

2009-04-22cfg80211: clean up includesJohannes Berg
Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

2009-04-22rtl8187: Implement TX/RX blink for LEDLarry Finger
The following patch implements some control over the LED on RTL8187B and RTL8187L devices. Triggers are registered for TX and RX. Whenever the trigger event occurs, the LED is turned off for 1/20 second, then turned back on. Note: For those RTL8187X devices that are built into the computer and have a LED that is expected to be controlled with a radio switch, this patch will not operate that LED. That will take a separate patch to be prepared later.

2009-04-22atheros: fix propagation of bad EEPROM on regulatory initLuis R. Rodriguez
When the EEPROM is not in good condition we cannot continue so we currently bail out but only ath5k is bailing out properly. Both ath9k and ar9170 were proceeding and if a user were to run into this they'd see an obscure panic. Lets propagate the error as intended and make sure we inform the user by lifting the error message from debug to a kernel error.

2009-04-22ath5k: manipulate rxlink and descriptor address under rxbuf lockBob Copeland
Grabbing an ath5k_buf then dropping the lock is racy because the referenced descriptor can be obtained in another thread and released before the buffer is handed to the hardware. Likewise, manipulating sc->rxlink without the lock can lead to having multiple self-linked hardware descriptors.

2009-04-22ath9k: reset after PCI FATAL/PERR interruptsSteven Luo
ath9k_hw_getisr() doesn't appear to set anything in the status mask for PCI FATAL or PERR interrupts (AR_INTR_SYNC_HOST1_FATAL/PERR), which the open-source HAL seems to do. This means that the card isn't reset after these interrupts. This patch seems to fix a problem where the wireless drops out with an "ath9k: received PCI FATAL interrupt" in dmesg after some time; the hardware is an AR5416 in an ASUS WL-500W running 2.6.28.7 (OpenWRT) and compat-wireless 2009-03-31.
