If we have new found information about our location and the

flag requirements we should be able to actively scan now on those
channels.
Since AP functionality is not allowed where passive scan flags are
set this means if you have a world regulatory domain and you get a
country IE that allows that channel (with active scan) then we lift
the passive-scan requirement so you can then use AP mode.

The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension.
So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being

Dynamically control the log verbosity with a module parameter.
This enables us to dynamically enable debugging messages (or disable
info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.
This increases the module size by about 3k. But in practice it reduces the
module size for the user, because some distributions ship the b43 module
with CONFIG_B43_DEBUG set, which increases the module by about 15k.
So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
There is no reason to keep it in a production-release kernel.
So we have a net reduction in size by about 12k.
This patch also adds a printk of the wireless core revision, so people
don't have to enable SSB debugging to get the wireless core revision.

First probe for proprietary firmware and then probe for opensource firmware.
This way around it's a win-win situation.
1) If proprietary fw is available, it will work.
2) If opensource firmware is available, but no proprietary (Distros can only ship open fw)
it might work.
3) If both open and proprietary are available, it will work, because it selects
the proprietary. We currently don't prefer the open fw in this case, because it doesn't
work on all devices. It would introduce a regression otherwise.

Current code for the RTL8187 is not returning valid retry information, thus the
rate-setting mechanism is not functioning. As a further complication, this info
is only obtained by reading a register, which cannot be read while in interrupt
context.
This patch implements the TX status return to mac80211 through the use of a
work queue.
One additional problem is that the driver currently enables the rate fallback
mechanism of the device, which conflicts with the mac80211 rate-setting
algorithm. This version of the patch disables rate fallback.

Atheros hardware supports 12 world regulatory domains, since these

Although we have 12 we can consolidate these into 5 structures based on

Sometime Tx reply rate different than what rate scale expecting
causing rate scale to bail out. This could cause failing to
commit LQ cmd. This patch will try to solve this instead of just
bail out. It also make sure we start with a valid rate.

allow user to set max rate through #iwconfig <inteface> rate XXX.
mac80211 will try to force this if user set it, but driver is not
in sync which cause mac80211 to report wrong current rate. This
patch will check if max rate is set and force it in rate scaling

remove static from config structures which will be used by new
hardware that is similar to 5000. This way the new devices
can use them without the new structures having to be stored in the
already overloaded iwl-5000.c file.

defining configurations that are not visible caused the following
entries to not be indented. changing the tree structure to name the
top level selection and have all others reference IWLWIFI directly
corrects this issue.

With the previously added tfd related ops, we can now use the iwl-tx.c host
command enqueue routine. Since the 3945 host command specific
routines are identical to the agn ones, we can just remove them from the 3945
code.
