compat-wireless: Update Readme to reflect changes

* A description of the differences of the stable and the normal version
  of compat wireless was added.
* Some outdated parts are now up to date
* replaceing the developing section with version in the wiki

These changes are needed because some people are tiring to build their
own compat-wireless version based on wireless-testing and some people
choose compat-wireless stable based on their currently running kernel
version.

Revert "compat-wireless: fix 07-change-default-rate-alg.patch"

This reverts commit fc4ed11ef1265b43e14bb3aa5bb4c6bd788ba65a.

In the linux-next tree there is this line
kparam_unblock_sysfs_write(ieee80211_default_rc_algo);
it was introduced 2 days ago. In wireless-text this does not exist for now.

This patch was added because it was not clear that compat-wireless is build on
linux-next.

mac80211: use netdev_attach_ops()

This simplifies mac80211's net_device_ops's backports
significantly. An unexpected benefit was the simplification
of the MQ backport, this is possible since the select_queue
callback can now simply be bacported by netdev_attach_ops()
selectively depending on the kernel used, the callback itself
can always be set on the ops structure since even older kernels
will have it on the code, it will just be unused.

Add linux-next cherry picked patches directory

We work hard to get patches in time onto the stable
tree but sometimes a few things slip out, and sometimes a
stable fix is simply too big in size to be merged into
stable. In such cases though we do believe some of these
patches are still relatively important to either enable new
hardware which escaped the late rc cycles or to correct some
behaviour which might be too late for stable. We apply
these patches by default as they will be supported on these
releases.

The larger the number of patches you see in this new directory
the more we should be ashamed. We should strive to reduce this
to 0 all the time.

This only makes sense for the stable compat-wireless releases
as bleeding edge compat-wireless already uses linux-next. We
add this patch into this tree though so that future stable
branches will get it as well.

Backport multiqueue support for kernels < 2.6.27

The 2.6.23 kernel added some initial multiqueue support.
That release relied on the on the notion of struct
net_device_subqueue attached to the netdevice struct
as an array. The 2.6.27 renamed these to struct netdev_queue,
and enhanced MQ support by providing locks separately onto
each queue. MQ support on 2.6.27 also extended each netdev
to be able to assign a select_queue callback to be used by
core networking for prior to pushing the skb out to the device
driver so that queue selection can be dealt with and
customized internally on the driver.

For kernels 2.6.23..2.6.26 then we backport MQ support by
using the equivalent calls on the struct netdev_queue to
the struct net_device_subqueue. The performance penalty
here is just that all these queues share a common lock
so stateful operations on one queue would imply a delay
on other queues.

For older kernels than 2.6.23 we can only stop all the
queues then and wake them up only if no other queue had
been stopped previously. This means for kernels older
than 2.6.23 there is a performance penalty and congestion
on one queue would imply propagating the same congestion
impact on all the other queues.

The select_queue callback was only added as of 2.6.27 via
commit eae792b7 so for kernels older than 2.6.23 and up
to 2.6.27 we must ensure we do the selection of the queue
once the core networking calls mac80211's dev_hard_start_xmit()
(ndo_start_xmit() callback on newer kernels).

This patch then consists of three parts:

  1) Addresses the lack of select_queue on older kernels than 2.6.27
  2) Extends the backport of net_device_ops for select_queue for kernels >= 2.6.27
  3) Backporting wake/stop queue for older kernels:
        - Handle with net_device_subqueue for >= 2.6.23
        - Treat each queue operation as an aggregate for all queues

Monitor interfaces have their own select_queue -- monitor interfaces
are used for injecting frames so they have their own respective queue
handling, but mac80211 just always sends management frames on VO
queue by using skb_set_queue_mapping(skb, 0) through ieee80211_tx_skb()
