wifi: mac80211: pass frame type to element parsing

2025-11-10T09:39:02+00:00

This will be needed for UHR operation parsing, and we already pass whether or not the frame is an action frame, replace that by the full type. Note this fixes a few cases where 'false' was erroneously passed (mesh and TDLS) and removes ieee802_11_parse_elems_crc() as it's unused.

wifi: mac80211: do not permit 40 MHz EHT operation on 5/6 GHz

2025-08-28T11:39:16+00:00

The EHT PHY requirements state that 80 MHz must be supported on the 5 and 6 GHz bands unless the STA is 20 MHz only. So if the channel width is limited to 40 MHz on a band other than 2.4 GHz, then disable EHT and downgrade to HE. The primary case where this can happen is if the hardware disables puncturing using IEEE80211_HW_DISALLOW_PUNCTURING.

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

wifi: mac80211: pass parsed TPE data to drivers

2024-05-23T08:35:04+00:00

Instead of passing the full TPE elements, in all their glory and mixed up data formats for HE backward compatibility, parse them fully into the right values, and pass that to the drivers. Also introduce proper validation already in mac80211, so that drivers don't need to do it, and parse the EHT portions. The code now passes the values in the right order according to the channel used by an interface, which could also be a subset of the data advertised by the AP, if we couldn't connect with the full bandwidth (for whatever reason.) Also add kunit tests for the more complicated bits of it.

wifi: mac80211: clean up connection process

2024-02-08T11:58:26+00:00

Rewrite the station-side connection handling. The connection flags (IEEE80211_DISABLE_*) are rather confusing, and they're not always maintained well. Additionally, for wider-bandwidth OFDMA support we need to know the precise bandwidth of the AP, which is currently somewhat difficult. Rewrite this to have a 'mode' (S1G/legacy/HT/...) and a limit on the bandwidth. This is not entirely clean because some of those modes aren't completely sequenced (as this assumes in some places), e.g. VHT doesn't exist on 2.4 GHz, but HE does. However, it still simplifies things and gives us a good idea what we're operating as, so we can parse elements accordingly etc. This leaves a FIXME for puncturing, this is addressed in a later patch.
