wifi: mac80211: handle 320 MHz in ieee80211_ht_cap_ie_to_sta_ht_cap

2023-11-24T17:42:18+00:00

The new 320 MHz channel width wasn't handled, so connecting
a station to a 320 MHz AP would limit the station to 20 MHz
(on HT) after a warning, handle 320 MHz to fix that.

wifi: mac80211: remove ampdu_mlme.mtx

2023-09-11T09:27:22+00:00

We now hold the wiphy mutex everywhere that we use or
needed the A-MPDU locking, so we don't need this mutex
any more. Remove it.

Most of this change was done automatically with spatch.

wifi: mac80211: convert A-MPDU work to wiphy work

2023-09-11T09:27:19+00:00

Convert the A-MPDU work to wiphy work so it holds the
wiphy mutex and we can later guarantee that to drivers.
It might seem that we could run these concurrently for
different stations, but they're all on the ordered
mac80211 workqueue, so this shouldn't matter for that.

wifi: mac80211: fix SMPS status handling

2023-09-11T09:27:18+00:00

The current SMPS status handling isn't per link, so we only
ever change the deflink, which is obviously wrong, it's not
even used for multi-link connections, but the request API
actually includes the link ID.

Use the new status_data changes to move the handling to the
right link, this also saves parsing the frame again on the
status report, instead we can now check only if it was an
SMPS frame.

Of course, move the worker to be a wiphy work so that we're
able to cancel it safely for the link.

wifi: mac80211: Fix SMPS handling in the context of MLO

2023-09-11T09:27:18+00:00

When the connection is a MLO connection, a SMPS request should be
sent on a specific link, as SMPS is BSS specific, and the DA and BSSID
used for the action frame transmission should be the AP MLD address, as
the underlying driver is expected to perform the address translation
(based on the link ID).

Fix the SMPS request handling to use the AP MLD address and provide the
link ID for the request processing during Tx.

wifi: mac80211: use wiphy work for SMPS

2023-06-07T17:53:22+00:00

SMPS requests are per link, and currently there's a potential
deadlock with canceling. Use the new wiphy work to handle SMPS
instead, so that the cancel cannot deadlock.

wifi: mac80211: Fix iTXQ AMPDU fragmentation handling

2023-01-10T12:24:17+00:00

mac80211 must not enable aggregation wile transmitting a fragmented
MPDU. Enforce that for mac80211 internal TX queues (iTXQs).

wifi: mac80211: keep A-MSDU data in sta and per-link

2022-09-06T08:17:08+00:00

The A-MSDU data needs to be stored per-link and aggregated into a single
value for the station. Add a new struct ieee_80211_sta_aggregates in
order to store this data and a new function
ieee80211_sta_recalc_aggregates to update the current data for the STA.

Note that in the non MLO case the pointer in ieee80211_sta will directly
reference the data in deflink.agg, which means that recalculation may be
skipped in that case.

wifi: mac80211: make smps_mode per-link

2022-09-06T08:11:44+00:00

The SMPS power save mode needs to be per-link rather than being shared
for all links. As such, move it into struct ieee80211_link_sta.
