      cfg80211: Extend channel to frequency mapping for 802.11j · 59eb21a6
      由 Bruno Randolf 提交于 
      Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.

This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.

The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
The drivers have been compile-tested only.

      wl12xx_sdio_test: rename files to match current style · 248daa08
      由 Luciano Coelho 提交于 
      Change some file names and Kconfig settings so that this new module matches
the new way of using wl12xx instead of wl1271.

Also fix SDIO power enabling and disabling to match the latest way of doing
it.

      wl12xx: Change TX queue to be per AC · 6742f554
      由 Juuso Oikarinen 提交于 
      With the current single-queue implementation traffic priorization is not
working correctly - when using multiple BE streams and one, say VI stream,
the VI stream will share bandwidth almost equally with the BE streams.

To fix the issue, implement per AC queues, which are emptied in priority
order to the firmware. To keep it relatively simple, maintain a global
buffer count and global queue stop/wake instead of per-AC.

With these changes, priorization appears to work just fine.

      wl12xx: allow runtime changing of debug_level · 17c1755c
      由 Eliad Peller 提交于 
      Currently, the debug level is set in compilation time (by the DEBUG_LEVEL
const). This method has the advantage of compiling only the relevant
messages, while optimizing out the unused ones.

In order to allow runtime control over the debug_level, while optimizing
out messages when debug messages are not needed, we combine some methods:
1. use dynamic_debug (pr_debug) rather then printk.
2. add debug_level module param in order to set debug level during insmod.
3. add debug_level sysfs file in order to allow dynamic control over the
   debug level.

Since patches for pr_debug_hex_dump() implementation haven't been applied yet,
we are still temporarly using print_hex_dump().

      wl1271: fixed problem with WPS IEs in probe requests · ea559b46
      由 Guy Eilam 提交于 
      Inclusion of a WPS IE in probe requests caused a problem
in the driver due to the maximum size of the probe request
template and the max_scan_ie_len values at initialization.

Increased the size of probe request template
to the maximum size allowed by the firmware.
Struct wl12xx_probe_req_template, which was only used
for calculating the max size of the probe request template,
is no longer used and needed.

max_scan_ie_len is used for validating the size of
additional IEs in scan requests.
Initialized the max_scan_ie_len field to the maximum size
of the probe request template minus the ieee80211 header size.

      wl12xx: add auto-arp support · c5312772
      由 Eliad Peller 提交于 
      The auto-arp feature of wl12xx allows the firmware to automatically
response to arp requests asking for its ip.

in order to use it, we configure the arp response template and
enable the corresponding bit in wl1271_acx_arp_filter (along with
passing its ip)

      wl1271_sdio_test: Add module for sdio RX/TX testing · b69eb80b
      由 Roger Quadros 提交于 
      This module enables individually generating RX and TX traffic
over the SDIO bus on which the WL1271 chipset is connected.
This is required to perform RF interference testing.

The module takes 2 module parameters 'rx' and 'tx'.

To generate RX traffic:
	modprobe wl1271_sdio_test rx=1
To generate TX traffic:
	modprobe wl1271_sdio_test tx=1

To generate both RX & TX traffic, set both rx and tx to 1.

You can change the testing configuration at runtime by changing
the rx & tx values at /sys/modules/wl1271_sdio_test/

To stop testing simply unload the module.

      wl12xx: disable 11a channels when wl->enable_11a is known · fb6a6819
      由 Luciano Coelho 提交于 
      Disabling the 11a channels when not supported in the reg_notify function was
not working as it should, because when the driver is initiailizing (and
registering itself with mac80211), it would get the reg notification too
early.  At that point the driver wouldn't have received the NVS yet, so it
wouldn't know whether 11a was supported.

To fix this, we disable 11a channels when we read the NVS instead.  Also, it
is easier (and still safe) to set n_channels to zero instead of setting the
disabled flag on every 11a channel.
