David Kilroy 9ee677c227 wireless: Add channel/frequency conversions to ieee80211.h
Added mappings for FHSS, DSSS and OFDM channels - with macros to point
HR DSSS and ERP to the DSSS mappings. Currently just static inline
functions.

Use the new functions in the older fullmac drivers. This eliminates a
number of const static buffers and removes a couple of range checks that
are now redundant.

Nick Kossifidis eaee7cc2c1 ath5k: More EEPROM code updates
* Don't scale power values on RF5111 EEPROMs because they get out of
  bounds (power is u8, so multiplying power by 50 is too much and there
  is no reason to do so -we don't do it on other chips anyway-). HAL
  does it as a technique to handle 0.5 dbm steps but i believe it's not
  the right thing to do and certainly not the right place to do it. We
  'll work this out on interpolation code for all chips (0.5 or 0.25
  steps etc) in a generic way.

 wrong power calibration info offset on RF2413+ chips)

*Initialize num_piers to 0 for RF2413 chips (note that we read 2GHz

 -usualy they are 0xff anyway but during my tests i got a 1 on b mode
 with no data- and use the newer eemap.

*Add some more comments (please forgive my poor English ;-( ) and

*Tested on 2425 and 2112 and has the same data with ath_info (i

Improve error message reporting when a frame was received
with unknown rate. Instead of using the boolean check if
the frame is supposed to be a PLCP value or not, we should
add a new mask (RXDONE_SIGNAL_MASK) which returns the type
identification for a signal value (i.e. PLCP). At the moment
we only have 2 different types, but more will arrive when
support for 11n is added.

Ivo van Doorn 5352ff6510 rt2x00: Restrict interface between rt2x00link and drivers
Restrict drivers to only access link_qual structure during
link tuning. The contents of these fields are for the drivers
and all fields are allowed to be changed to values the driver
considers correct.

This means that some fields need to be moved outside of this
structure to restrict access only to rt2x00link itself.
This allows some code to be moved outside of the rt2x00.h header
and into rt2x00link.c.

Ivo van Doorn eb20b4e8a6 rt2x00: Reduce calls to bbp_read()
The link_tuner() function will always call bbp_read()
at the start of the function. Because this is an
indirect register access has some costs attached
to it (especially for USB hardware).

We already store the value read from the register
into the vgc_level value inside the link structure.
Instead of reading from the register we can read that
field directly and base the tuner on that value.

This reduces the time the registers are locked with
the csr_mutex and speeds up the link_tuner processing.

In ieee80211_sta structure there is u64 supp_rates[IEEE80211_NUM_BANDS]
this is filled with all support rate from assoc_resp.  If we associate
with G-band AP only supp_rates of G-band will be set the other band
supp_rates will be set to 0. If the user type this command
this will cause mac80211 to set to new channel, mac80211
does not disassociate in setting new channel, so the active
band is now A-band. then in handling the new essid mac80211 will
kick in the assoc steps which involve sending disassociation frame.
in this mac80211 will WARN_ON sta->supp_rates[A_BAND] == 0.

Steve Glendinning 0b491eee46 usbnet: allow type check of devdbg arguments in non-debug build
Improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h).  This makes no change to the resulting size of
usbnet modules.

This patch also removes an #ifdef DEBUG directive from rndis_wlan so
it's devdbg statements are always type-checked at compile time.

Rami Rosen e223b6dc05 rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().
When running modprobe rt73usb, and then rmmod rt73usb, and then
iwconfig, the wlan0 device does not disappear. When repeating this
process again, we get a kernel Oops errors and "BUG: unable to handle
kernel paging request..." message in the kernel log.

The reason for this is that there is an error in rt2x00rfkill_free(),
which is called in the process of removing the device
(rt2x00lib_remove_dev() in rt2x00dev.c).
rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is
bit number 1 () in rt2x00dev->flags instead of in
rt2x00dev->rfkill_state. As a result, when checking the
DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in
rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call
ieee80211_unregister_hw().

This patch corrects this: the parameter for __test_and_clear_bit() in
rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not
&rt2x00dev->flags.

Zhu Yi 73e1a65d3c iwlwifi: remove CMD_WANT_SKB flag if send_cmd_sync failure
In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
the cmd comes in later, it will possibly set an invalid address. Thus
it causes an invalid memory access.

This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.

Jouni Malinen b657eade2f ath9k: Fix an operator typo in phy rate validation
This was not supposed to be a bitwise AND operation, but a check of
two separate conditions. Anyway, the old code happened to result in
the same behavior, so this is just changing the code to be easier to
understand and also to keep sparse from warning about dubious
operators.

Andrey Yurovsky d71038c059 libertas: Fix alignment issues in libertas core
Data structures that come over the wire from the WLAN firmware must be packed.
This fixes alignment problems on the blackfin architecture and, reportedly, on
the AVR32.

This is a replacement for the previous version of this patch which had also
explicitly used get_unaligned_ macros.  As Johannes Berg pointed out, these
macros were unnecessary.
