For MLO, we cannot use vif->bss_conf.chandef.chan->band, since that will lead to a NULL-ptr dereference as bss_conf isn't used. However, in case of real MLO, we also need to take both LMACs into account if they exist, since the station might be active on both LMACs at the same time. Signed-off-by:

Track instead whether or not the station was authorized, that's clearer than trying to indicate in the code whether or not the full bandwidth should be used via an 'update' argument. While at it, give rs_fw_rate_init() the iwl_mvm_ prefix. Signed-off-by:

When allocating a new link station, initialize the ratescaling data for it. To do that, refactor the initialization code out into a new iwl_mvm_rs_add_sta_link() function. Signed-off-by:

We need to look up the correct version of this struct depending on the interface type, rather than just checking if the pointer is non-NULL. Fix that.

Since only clients to an AP can be 20MHz-only STAs, adjust the code to not make the use of EHT capabilities depend on only the bandwidth, but also the type of interface. Fixes: 701404f1 ("wifi: iwlwifi: rs: add support for parsing max MCS per NSS/BW in 11be") Signed-off-by:

When this is called it might crash due to the use of deflink's phy context, update all links instead. It really shouldn't be called right now though, but it's better to have safer code until we update this to be with a link parameter. Signed-off-by:

When we first add the STA before sending an authentication frame this is false. However, in some cases such as FT or certainly in MLO link switch scenarios, it will be true. If it happens to be true, it causes a firmware assert (in LMAC, 0x2528), because the same bit is used by the firmware for tracking this setting as well as for tracking if the management key has been installed, and then we get this assert from the firmware when installing the MFP key as it thinks it has already been installed. Remove the setting for now, until the firmware disentangles the two. We should be able to set it, in fact we should be setting it speculatively before authentication/association, to avoid processing management frames that should have been protected/encrypted before the key is set.

A long time, ago in commit 818965d3 ("cfg80211: Allow a scan request for a specific BSSID"), the stack started passing the BSSID that should be scanned for. Use it in iwlwifi for the intended optimisation, and to also allow the use of this for an implementation sending multi-link probe requests. Signed-off-by:

The initiator smooth list is initialized only in iwl_mvm_up(), but is cleared in iwl_mvm_mac_stop. This may result in iterating over the list before it was initialized in case iwl_mvm_up() failed early. Fix it by moving the list initialization to an earlier stage.

In iwl_mvm_mac_ctxt_get_lowest_rate() we were still accessing vif->bss_conf without any multi-link provisions, and also the info->band, both of which isn't valid in MLO.
