2023-03-30wifi: iwlwifi: mvm: initialize max_rc_amsdu_len per-linkBenjamin Berg
Initialize max_rc_amsdu_len per-link both on state change and when a new link is added.

2023-03-30wifi: iwlwifi: mvm: use the new lockdep-checking macrosJohannes Berg
Use the new macros from mac80211 that do lockdep checking on the RCU dereferences, instead of hard-coding 1 as the argument to rcu_dereference_protected().

2023-03-30wifi: iwlwifi: mvm: rxmq: report link ID to mac80211Johannes Berg
Add a fw_id_to_link_sta array in mvm to track the link STA for each firmware station ID, and then use that to report the link a frame was received on (since we know the station ID from firmware). Notably, this fixes beacon tracking for the correct link since mac80211 now queues and processes those on the one link identified by the link ID only.

2023-03-30wifi: iwlwifi: mvm: use the link sta addressShaul Triebitz
Replace the deflink.addr with the proper link address for setting the peer_link_address in the station command. For a non-MLD station, it will be the deflink.

2023-03-30wifi: iwlwifi: mvm: use STA link addressJohannes Berg
For now we only support a single link, so just use the deflink's address for the link address, instead of the STA's (MLD) address, but use the link address anyway in order to facilitate MLO connections.

2023-03-30wifi: iwlwifi: mvm: add fw link id allocationGregory Greenman
Driver uses link_id as an index in the array. FW currently can support only 2 concurrently active links per vif with the ids in the range 0-3. Add a mapping of dirver link ids to fw link id and track the number of active link ids.

2023-03-30wifi: iwlwifi: mvm: adjust internal stations to MLOGregory Greenman
Internal stations are mcast/bcast and sniffer. They need some link specific data like bss id/phy id. Add link_conf as a parameter.

2023-03-30wifi: iwlwifi: mvm: align to the LINK cmd update in the FWMiri Korenblit
The LINK cmd host api has been updated. Align the driver to the new changes. Also, temporary use mac_id for link_id. Using the phy_id as the link_id is wrong since we might have 2 macs operating on the same phy - in this case we will have 2 different links (one for each mac) with the same link_id. On the other hand, since we don't have MLO implemented yet, we won't have 2 different links of the same mac. Therefore, we can use the mac_id as the link_id.

2023-03-30wifi: iwlwifi: mvm: always use the sta->addr as the peers addrMiri Korenblit
Currently we're setting the sta->addr as the peers address only if the iftype is NL80211_IFTYPE_AP, otherwise we are setting the bssid to be the addr. This causes bugs in TDLS. Fix this by always using the sta->addr.

These flows are the same in both MLD API and the current API, except for the commands that are being sent during this flows. Instead of checking each time before calling these floews what API we use and then call the correct function, call always the old one, which in turn will call the new one in case we're using the MLD API.

2023-03-30wifi: iwlwifi: mvm: sta preparation for MLOGregory Greenman
Split iwl_mvm_sta into general and link specific parts. As a first step, all link dependent parameters reside in deflink.

2023-03-30wifi: iwlwifi: mvm: vif preparation for MLOGregory Greenman
In MLO, some fields of iwl_mvm_vif should be defined in the context of a link. Define a separate structure for these fields and add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy code will use only deflink object while MLO related code will use the corresponding link from the link array. It follows the strategy applied in mac80211 for introducing MLO changes. The below spatch takes care of updating all driver code to access fields separated into MLD specific data structure via deflink (need to convert all references to the fields listed in var to deflink.var and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field). @iwl_mld_vif@ struct iwl_mvm_vif *v; struct ieee80211_vif *vv; identifier fn; identifier var = {bssid, ap_sta_id, bcast_sta, mcast_sta, beacon_stats, smps_requests, probe_resp_data, he_ru_2mhz_block, cab_queue, phy_ctxt, queue_params}; @@ ( v-> - var + deflink.var | fn(vv)-> - var + deflink.var ) Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Link: https://lore.kernel.org/r/20230328104948.4896576f0a9f.Ifaf0187c96b9fe52b24bd629331165831a877691@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>
