wifi: mac80211: fix CRC calculation for extended elems

2023-06-21T12:01:28+00:00

For extended elements, we currently only calculate the CRC
for some of them, but really we should do it also for the
rest that we care about, such as EHT operation and multi-
link.

Also, while at it, it seems we should do it even if they
aren't well-formed, so we notice if that changes.

wifi: mac80211: Include Multi-Link in CRC calculation

2023-06-19T10:05:30+00:00

Include the Multi-Link elements found in beacon frames
in the CRC calculation, as these elements are intended
to reflect changes in the AP MLD state.

wifi: mac80211: Remove "Missing iftype sband data/EHT cap" spam

2023-06-19T10:05:26+00:00

In mesh mode, ieee80211_chandef_he_6ghz_oper() is called by
mesh_matches_local() for every received mesh beacon.

On a 6 GHz mesh of a HE-only phy, this spams that the hardware does not
have EHT capabilities, even if the received mesh beacon does not have an
EHT element.

Unlike HE, not supporting EHT in the 6 GHz band is not an error so do
not print anything in this case.

Merge wireless into wireless-next

There are some locking changes that will later otherwise
cause conflicts, so merge wireless into wireless-next to

wifi: mac80211: Add getter functions for vif MLD state

2023-06-14T10:20:08+00:00

As a preparation to support disabled/dormant links, add the
following function:

- ieee80211_vif_usable_links(): returns the bitmap of the links
  that can be activated. Use this function in all the places that
  the bitmap of the usable links is needed.

- ieee80211_vif_is_mld(): returns true iff the vif is an MLD.
  Use this function in all the places where an indication that the
  connection is a MLD is needed.
