Remove fw_active_links_num counter since we now have a bitmap of active links in vif. Also, update link activation status only when LINK_CONTEXT_MODIFY_ACTIVE bit set in changes parameter. Signed-off-by:

Here we always have a link ID, not MAC ID, so clean up the naming. Signed-off-by:

When we remove the station, we call iwl_mvm_sta_del() which returns true if we cannot remove it from the firmware yet, which happens if this is the station ID for the AP station that's still used because the MAC is still associated. However, we still must free the link data as the station is only kept alive in the firmware, in mac80211 and driver the data structures are destroyed. To fix that, we need to make iwl_mvm_mld_free_sta_link() track whether or not the station is still alive in FW, as otherwise we might reuse the station ID in the meantime and iwl_mvm_mld_rm_sta_from_fw() would reject the later delete from the firmware. Add an argument to it for that. Then we can use the return value of iwl_mvm_sta_del() for that to fix the issue, and call iwl_mvm_mld_rm_sta_from_fw() only if we need to not keep the station in FW.

We were still using the deflink in most cases, update the code to use the appropriate link. Signed-off-by:

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(). Signed-off-by:

During link switching there might be a link that's marked active but has no chanctx assigned (so it's not active from our driver's POV), skip such links in power recalculation without any warning. Signed-off-by:

If we change only idle, avoid sending the MAC context command since it doesn't depend on idle state. This also fixes an issue with the firmware because without this we send the command during link switching, as we just deactivated the first link, and we cannot send this command when there's no active link.

When we remove the AP station, we iterate over the links and remove all the keys, however, the key iteration will return all keys for all links, so skip the ones that we don't need based on the link ID. Signed-off-by:

When iterating station links, skip the links that are not yet active by checking for mvmvif->link[] existence. Signed-off-by:

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. Signed-off-by:

For an MLD AP, use the correct link mcast or bcast station id. Signed-off-by:

For management frames sent by an AP interface, translate the MLD addresses to LINK addresses (for an MLD AP). AP (non-bufferable) management frames are sent via the broadcast station so the translation cannot be done by the firmware. Signed-off-by:

Add/removed from iwl driver and firmware station links. Update the station queues accordingly (which station links are connected to the station queues). Signed-off-by:

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. Signed-off-by:

Rate scale initialization needs some parameters stored separately for each link. Pass link_conf and link_sta pointers and adjust the relevant code accordingly. Signed-off-by:

Make the decision about radar detection status depending on each active MLO link. Signed-off-by:

It has to be done per link. We still don't support keys configuration for several links, but the single vif link can still point to a link different from deflink. For now handle the removal of keys for the default link. Signed-off-by:

We're hitting these while starting to enable MLO in the driver, but getting them each and every time isn't very useful one way or the other. Make these warnings trigger only once. Signed-off-by:

Iterate all the links here and check which ones are active, then adjust them accordingly. This is still wrong as far as the RSSI event is concerned (calling iwl_mvm_bt_coex_enable_rssi_event) since we call that now multiple times, which could overwrite the data; we need to either make that per link or call it only once, but need to sort out first what the firmware will be doing for beacon filtering/beacon abort in MLO.

This is more of a workaround, with MLO we can get here with the deflink not assigned. It's not critical right now that we have this right, so WARN_ON_ONCE() and don't crash until we can fix this area of the code. Signed-off-by:

Johannes Berg authored
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. Signed-off-by:

For now, if using MLO, skip the MEI update. It probably needs new API for multiple channels. Signed-off-by:

This needs to apply to the link, not deflink. Signed-off-by:

With newer MLD firmware API we no longer need beacon timing information from the host, so disable TIMING_BEACON_ONLY. If MLO is enabled (currently only for testing), then we must not have DEAUTH_NEED_MGD_TX_PREP because mac80211 doesn't support it yet, we'll have to fix that later. Signed-off-by:

Implement the link change ops for links and stations. Note that the stations one is empty for now as we only have support for a single link so far, and then the stations are created with the first link as deflink by mac80211, so right now we don't really need anything. Signed-off-by:

vif->bss_conf is used in this function only when TLC is not offloaded, so not in MLO flow. Simplify the related "if" condition and call iwl_mvm_hwrate_to_tx_status() only for driver rate scale. Signed-off-by:

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. Signed-off-by:

These are two new handlers for MLO. As the configurations done in bss_info_changed() are now split into two separate flows, use MLO specific implementation instead of common functions with the non-MLO code. Signed-off-by:

In newer firmware APIs the firmware is responsible for tracking the DTIM period and other beacon timing, so we don't need to wait with setting associated. In real MLO operation, mac80211 isn't tracking this anyway, and connections wouldn't work. Signed-off-by:
