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

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

libertas: add support for Marvell SD8688 chip
Use RxPD->pkt_ptr to locate eth803 header in the packet

Set SDIO block size to 256 for CMD53.
The maximum block size for SD8688 WLAN function is set

results upto 2K bytes data (4 blocks) being transferred

Convert scan function to cfg80211. Unlike old scan code new code
waits 1 sec before getting scan data from device and passing
forward to cfg80211.

This patch hopefully finishes the SoftLED code:
- It adds two more LEDs (rx and radio).
(the FW claims it can support up to 16 LEDs,
but I doubt that any vendor put more than 4 on a board)
- update the LEDs in a _delayed_ workqueue.
No one reported any more crashes.
(see: "PATCH] p54: fix race condition in memory management")
So we can stop burning the mm code.

Claiming every available 5 ghz channel has a couple of negative
side-effects: scanning takes a long time, and the channel list
overflows the available buffer space for netlink commands,
resulting in:
$ iw phy phy0 info
command failed: No buffer space available (-105)
This patch adds a modparam so people who want to see all the channels
can do so by passing all_channels=1. By default users will see a
smaller list of channels. This also halves scan time, from 10 seconds
down to less than 5 when using world regulatory.

This patch fixes a bug in checking for HT40 mode.
The STA's mode can be determined from the cached HT capabilities,
use that and remove the redundant variable 'rc_phy_mode'.

Using a u32 to store a single flag is overkill.
Use a bool to store whether the buffer is stale or not.
Also, use u8 instead of u32 to store the buffer type.
