[v5,00/11] wifi: cfg80211/mac80211: improve support for multiple radios

Message

Felix Fietkau Oct. 9, 2024, 8:25 a.m. UTC

This series adds support for restricting vifs to a set of radios.
The allowed radios mask is used to restrict scanning, off-channel activity,
and can be used by the driver to selectively enable monitoring and manage
radio state.
It also adds support for monitoring on multiple channels at the same time.

Changes since RFC:
 - split cfg80211 and mac80211 changes
 - remove mac80211 per-radio tracking for monitor state
 - remove per-radio start/stop calls
 - remove radio index from rx status
 - rewrite multi-channel monitor support

Changes since PATCH:
 - fix commit commit descriptions regarding remain-on-channel
 - fix return code in ibss scan change
 - fix wdev->radio_mask initialization

Changes since PATCH v2:
 - fix build error with tracing on .set_monitor_channel change

Changes since PATCH v3:
 - fix another tracing build error

Changes since PATCH v4:
 - add missing documentation
 - clean up commit description and return code handling for ibss scan
 - do not report invalid radio antenna mask

Felix Fietkau (11):
  wifi: cfg80211: add option for vif allowed radios
  wifi: mac80211: use vif radio mask to limit ibss scan frequencies

  wifi: mac80211: remove status->ampdu_delimiter_crc
  wifi: cfg80211: pass net_device to .set_monitor_channel
  wifi: mac80211: add flag to opt out of virtual monitor support
