wifi: cfg80211: Add link_id to cfg80211_ch_switch_started_notify()

2022-08-25T09:07:26+00:00

Add link_id parameter to cfg80211_ch_switch_started_notify() to allow
driver to indicate on which link channel switch started on MLD.

Send the data to userspace so it knows as well.

wifi: cfg80211: Add link_id parameter to various key operations for MLO

2022-08-25T08:41:05+00:00

Add support for various key operations on MLD by adding new parameter
link_id. Pass the link_id received from userspace to driver for add_key,
get_key, del_key, set_default_key, set_default_mgmt_key and
set_default_beacon_key to support configuring keys specific to each MLO
link. Userspace must not specify link ID for MLO pairwise key since it
is common for all the MLO links.

wifi: cfg80211/nl80211: move rx management data into a struct

2022-07-22T12:28:26+00:00

The functions for reporting rx management take many arguments.
Collect all the arguments into a struct, which also make it easier
to add more arguments if needed.

wifi: cfg80211/mac80211: Support control port TX from specific link

2022-07-15T09:43:19+00:00

In case of authentication with a legacy station, link addressed EAPOL
frames should be sent. Support it.

wifi: cfg80211: extend cfg80211_rx_assoc_resp() for MLO

2022-07-15T09:43:17+00:00

Extend the cfg80211_rx_assoc_resp() to cover multiple
BSSes, the AP MLD address and local link addresses
for MLO.

wifi: cfg80211: adjust assoc comeback for MLO

2022-07-15T09:43:17+00:00

We only report the BSSID to userspace, so change the
argument from BSS struct pointer to AP address, which
we'll use to carry either the BSSID or AP MLD address.

wifi: cfg80211: prepare association failure APIs for MLO

2022-07-15T09:43:16+00:00

For MLO, we need the ability to report back multiple BSS
structures to release, as well as the AP MLD address (if
attempting to make an MLO connection).

Unify cfg80211_assoc_timeout() and cfg80211_abandon_assoc()
into a new cfg80211_assoc_failure() that gets a structure
parameter with the necessary data.

wifi: cfg80211: remove BSS pointer from cfg80211_disassoc_request

2022-07-15T09:43:16+00:00

The race described by the comment in mac80211 hasn't existed
since the locking rework to use the same lock and for MLO we
need to pass the AP MLD address, so just pass the BSSID or
AP MLD address instead of the BSS struct pointer, and adjust
all the code accordingly.

wifi: cfg80211: drop BSS elements from assoc trace for now

2022-07-15T09:43:14+00:00

For multi-link operation, this cannot work as the req->bss pointer
will be NULL, and we'll need to do more work on this to really add
tracing for the MLO case here. Drop the BSS elements for now as
they're not the most useful thing, and it's hard to size things
correctly for the MLO case (without adding a lot of code that's
also executed when tracing isn't enabled.)

wifi: cfg80211/mac80211: separate link params from station params

2022-07-15T09:43:13+00:00

Put the link_station_parameters structure in the station_parameters
structure (and remove the station_parameters fields already existing
in link_station_parameters).
Now, for an MLD station, the default link is added together with
the station.
