wifi: mac80211: add ieee80211_vif_link_active() helper

2024-03-04T13:32:53+00:00

We sometimes need to check if a link is active, and this is complicated by the fact that active_links has no bits set when the vif isn't (acting as) an MLD. Add a small new helper ieee80211_vif_link_active() to make that a bit easier, and use it in a few places.

wifi: mac80211: fix supported rate masking in scan

2024-03-04T13:24:27+00:00

We have an nl80211 attribute to mask supported rates from probe responses in scanning, e.g. for use in P2P, but in the refactoring I stopped applying this mask. Restore it.

wifi: mac80211: start building elements in SKBs

2024-02-08T14:00:43+00:00

The building of elements is really mess, and really the only reason we're not doing it in SKBs in the first place is that the scan code in ieee80211_build_preq_ies() doesn't. Convert ieee80211_build_preq_ies() to use an SKB internally so that we can gradually convert other things to ..._put_*() style interfaces.
