[PATCH v3 0/5] Introduce 802.11ax bss coloring support

[Lorenzo Bianconi]

Changes since v2:
- improve collision reporting procedure taking into account first and last
  collision report timestamp
- add partial CCA support for (re)assoc response

Changes since v1:
- use os_get_reltime and os_reltime instead.
- use bool cca_in_progress.
- use random BSS color to avoid hardcoded BSS color value of 1.
- modify comment for DOT11BSS_COLOR_COLLISION_AP_PERIOD.
- add a note for collision behavior.
- fix compiler warnings.
- Be clear in the commit message regarding hostapd_switch_color().

John Crispin (5):
  bss coloring: add support for handling collision events and triggering
    CCA
  bss_coloring: add the code required to generate the CCA IE
  bss coloring: disable BSS color during CCA
  bss coloring: add the switch_color handler to the nl80211 driver
  bss coloring: handle the collision and CCA events coming from the
    kernel
