 * no longer build its own probe request, but use mac80211's
 * therefore, support arbitrary scan IEs (up to the max len)
 * support multiple scan SSIDs

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.

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.

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.

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.

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.

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
