wifi: cfg80211: allow setting extended MLD capa/ops

2025-03-11T09:51:59+00:00

Some extended MLD capabilities and operations bits (currently
the "BTM MLD Recommendataion For Multiple APs Support" bit)
may depend on userspace capabilities. Allow userspace to pass
the values for this field that it supports to the association
and link reconfiguration operations.

wifi: cfg80211: send MLO links tx power info in GET_INTERFACE

2024-12-04T15:14:46+00:00

Currently, TX power is reported on interface/wdev level as
part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links
can be part of an interface/wdev and hence its necessary to
report the TX power of each link.

Add support to send tx power for all valid links of an MLD as
part of NL80211_CMD_GET_INTERFACE request.

As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.

wifi: cfg80211: handle DFS per link

2024-09-06T11:01:05+00:00

Currently, during starting a radar detection, no link id information is
parsed and passed down. In order to support starting radar detection
during Multi Link Operation, it is required to pass link id as well.

Add changes to first parse and then pass link id in the start radar
detection path.

Additionally, update notification APIs to allow drivers/mac80211 to
pass the link ID.

However, everything is handled at link 0 only until all API's are ready to
handle it per link.

wifi: trace: unlink rdev_end_cac trace event from wiphy_netdev_evt class

2024-09-06T11:01:04+00:00

rdev_end_cac trace event is linked with wiphy_netdev_evt event class.
There is no option to pass link ID currently to wiphy_netdev_evt class.
A subsequent change would pass link ID to rdev_end_cac event and hence
it can no longer derive the event class from wiphy_netdev_evt.

Therefore, unlink rdev_end_cac event from wiphy_netdev_evt and define it's
own independent trace event. Link ID would be passed in subsequent change.

wifi: cfg80211: add regulatory flag to allow VLP AP operation

2024-06-12T11:04:25+00:00

Add a regulatory flag to allow VLP AP operation even on
channels otherwise marked NO_IR, which may be possible
in some regulatory domains/countries.

Note that this requires checking also when the beacon is
changed, since that may change the regulatory power type.
