[PATCHv6 00/18] Add support for 5 and 10 MHz channels

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset adds support for 5 and 10 MHz in nl80211/cfg80211/mac80211
and enables support in ath5k and ath9k, which already support this feature
on the driver side. 5 and 10 MHz wide channels might be useful for:

 * long shot links, as the transmissions are more robust
 * future support for 802.11y which allows some 5 and 10 MHz channels in
   3.6 GHz range
 * future support for 802.11p which uses 10 MHz in 5.9 GHz range
 * ... and more "special" applications.

This patchset enables 5 and 10 MHz channels only for OFDM, and without
HT/MIMO/aggregation (for now). Support may be added later.

Changes to PATCHv5:

 * fix compile error/warnings when applying only parts of the patchset,
   move patch "mac80211: add radiotap flag and handling for 5/10 MHz" in front
   for the same reason
 * remove useless whitespace

As always, any comments are appreciated!
Cheers,
        Simon


Simon Wunderlich (18):
  nl80211: add scan width to bss and scan request structs
  mac80211/rc80211: add chandef to rate initialization
  mac80211: fix timing for 5 MHz and 10 MHz channels
  mac80211: add radiotap flag and handling for 5/10 MHz
  mac80211: select and adjust bitrates according to channel mode
  cfg80211/mac80211: get mandatory rates based on scan width
  cfg80211/mac80211: use reduced txpower for 5 and 10 MHz
  mac80211: allow scanning for 5/10 MHz channels in IBSS
  mac80211: return if IBSS chandef can not be used
  nl80211: allow 5 and 10 MHz channels for IBSS
  ath9k: always use SIFS times from OFDM for 5/10 MHz
  ath9k: use chandef instead of channel_type
  ath9k: report 5/10 MHz channels
  ath9k: set 5/10 MHz supported channels and fix bitrate
  ath9k: announce that ath9k supports 5/10 MHz
  ath5k: report 5/10 MHz channels
  ath5k: set 5/10 MHz supported channels and fix duration
  ath5k: enable support for 5 MHz and 10 MHz channels
