When IBSS is fixed to a frequency, it can still
scan to try to find the right BSSID. This makes
sense if the BSSID isn't also fixed, but it need
not scan all channels -- just one is sufficient.
Make it do that by moving the scan setup code to
ieee80211_request_internal_scan() and include
a channel variable setting.

Note that this can be further improved to start
the IBSS right away if both frequency and BSSID
are fixed.

This allows enabling TX and disabling both TX and
RX aggregation sessions manually in debugfs. It is
very useful for debugging session initiation and
teardown problems since with this you don't have
to force a lot of traffic to get aggregation and
thus have less data to analyse.

Also, to debug mac80211 code itself, make hwsim
"support" aggregation sessions. It will still just
transfer the frame, but go through the setup and
teardown handshakes.

This driver uses the core orinoco modules for the bulk of
the functionality. The low level hermes routines (for local bus
cards) are replaced, the driver supplies its own ndo_xmit_start
function, and locking is done with the _bh variant.

Some recent functionality is not available to the USB cards yet
(firmware loading and WPA).

Local bus and USB drivers will need to do locking differently.

The original orinoco_usb patches had a boolean variable controlling
whether spin_lock_bh was used, or irq based locking. This version
provides wrappers for the lock functions and the drivers specify the
functions pointers needed.

This will introduce a performance penalty, but I'm not expecting it to
be noticable.

Both of these functions can currently return

This is just a cleanup and doesn't change how the code works.

debugfs_create_dir() and debugfs_create_file() return an error pointer
(-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs
they return NULL.  This is how they are implemented and what it says in
the DebugFS documentation.  DebugFS can not be compiled as a module.

As a result, we only need to check for error pointers and particularly
-ENODEV one time to know that DebugFS is enabled.  This patch keeps the
first check for error pointers and removes the rest.

The other reason for this patch, is that it silences some Smatch warnings.
Smatch sees the condition "(result != -ENODEV)" and assumes that it's
possible for "result" to equal -ENODEV.  If it were possible it would lead
to an error pointer dereference.  But since it's not, we can just remove
the check.

Update the rfcsr and bbp init code for SoC devices to match with the
latest Ralink driver.

To have better control over which values are used for the register
initialization create a new function rt2800_is_305x_soc which checks
for SoC interface type, the correct RT chipset and the correct RF
chipset. This is based on the assumption that all rt305x SoC devices
use a rt2872 and rf3020/rf3021/rf3022.

In case an unknown RF chipset is found on a SoC device with a rt2872
don't treat it as rt305x and just print a message.

The driver had a join command without keep-alive restart procedures in the
channel changing code. After associated scans, the mac80211 does re-set the
current channel, causing the join to occur. This would stop the hardware
keep alive.

To make the joins safer in this respect, this patch adds a join function that
does the hardware-keep-alive magic along the join. This is now invoked in the
above mentioned scenario, and also other scenarios.

In testing I noticed that the wl1271 commands fall into two categories. In the
first category are "fast" commands, these mostly take only 0 or 1 polls to
complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the
second category, the command completion takes well more than 0.5ms (from
1.5ms upwards.)

This patch fixes command polling such that it is optimal for the fast commands,
but also allows sleep for the longer ones.
