      mac80211: revamp beacon configuration · 9d139c81
      由 Johannes Berg 提交于 
      This patch changes mac80211's beacon configuration handling
to never pass skbs to the driver directly but rather always
require the driver to use ieee80211_beacon_get(). Additionally,
it introduces "change flags" on the config_interface() call
to enable drivers to figure out what is changing. Finally, it
removes the beacon_update() driver callback in favour of
having IBSS beacon delivered by ieee80211_beacon_get() as well.

      mac80211: use hardware flags for signal/noise units · 566bfe5a
      由 Bruno Randolf 提交于 
      trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.

this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.

for signal:

  IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
  IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
  IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW

for noise we currently only have dBm:

  IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW

if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.

i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

      zd1211rw: initial IBSS support · 84e6dc9a
      由 Bruno Randolf 提交于 
      this adds initial IBSS support for the zydas zd1211rw:
convince driver that it can do IBSS mode. add mac80211 beacon_update callback.

IBSS merge and TSF updates don't work yet, but it makes the driver usable in
ad-hoc networks.

      zd1211rw: Fix beacon filter flags thinko · 2c1a1b12
      由 Michael Buesch 提交于 
      We must not clear the FIF_BCN_PRBRESP_PROMISC bit in the
new_flags. The zd-driver does support sending beacons and
probe responses to the host. What the flag does is say "Send me
all beacons and probe responses". And we actually do that. We always
do that, so we ignore the case when the bit is disabled. But that is
fine. But we must not clear the flag, as that tells mac80211 that
we do not support passing beacons and probe responses to the stack.
And that's not true.

      cfg80211 API for channels/bitrates, mac80211 and driver conversion · 8318d78a
      由 Johannes Berg 提交于 
      This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.

Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.

Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.

I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.

      zd1211rw: Fix alignment problems · 93137943
      由 Ulrich Kunitz 提交于 
      Shaddy Baddah found an alignment problem with zd1211rw driver at
2007-11-19. This patch fixes it, it is based on the patch proposed by
Herbert Xu. The alignment 4 has been the agreed value on the
linux-wireless mailing list.

Notify that the problem does only affect the old zd1211rw softmac
driver and not the zd1211rw-mac80211 driver. Daniel Drake has
already provided a patch for the replacement of the softmac
driver, which this patch will break.
