If we add 6 GHz capability in MLO, we cannot use the SMPS mode from the deflink. Pass it separately instead since on a second link we don't even have a link data struct yet. Signed-off-by:

From 'IEEE Std 802.11-2020 section 11.8.8.4.1': The mesh channel switch may be triggered by the need to avoid interference to a detected radar signal, or to reassign mesh STA channels to ensure the MBSS connectivity. A 20/40 MHz MBSS may be changed to a 20 MHz MBSS and a 20 MHz MBSS may be changed to a 20/40 MHz MBSS. Since the standard allows the change of bandwidth during the channel switch in mesh, remove the bandwidth check present in ieee80211_set_csa_beacon.

Commit 177577db ("wifi: mac80211: sta_info: fix link_sta insertion") makes ieee80211_sta_activate_link() return 0 in the 'hash' label case. Hence, setting ret in the !test_sta_flag(...) branch to zero is not needed anymore and can be dropped. Remove a needless assignment. No functional change. No change in object code. Signed-off-by:

In ieee80211_tx_dequeue() we currently allow a control port frame to be transmitted on a non-authorized port only if the A2 matches the local interface address, but if that's an MLD and the peer is a legacy peer, we need to allow link address here. Fix that. Signed-off-by: -
Johannes Berg authored
For an AP interface, when userspace specifieds the link ID to transmit the control port frame on (in particular for the initial 4-way-HS), due to the logic in ieee80211_build_hdr() for a frame transmitted from/to an MLD, we currently build a header with A1 = DA = MLD address of the peer MLD A2 = local link address (!) A3 = SA = local MLD address This clearly makes no sense, and leads to two problems: - if the frame were encrypted (not true for the initial 4-way-HS) the AAD would be calculated incorrectly - if iTXQs are used, the frame is dropped by logic in ieee80211_tx_dequeue() Fix the addressing, which fixes the first bullet, and the second bullet for peer MLDs, I'll fix the second one for non-MLD peers separately.

The next patch will require splitting the data here into AP and non-AP because for EHT, the format of the MCS/NSS support (struct ieee80211_eht_mcs_nss_supp) is different, for AP the only_20mhz cannot be used. Signed-off-by: -

In MLO, when the address translation from link to MLD is done in fw/hw, it is necessary to be able to have some information on the link on which the frame has been received. Extend the rx API to include link_id and a valid flag in ieee80211_rx_status. Also make chanes to mac80211 rx APIs to make use of the reported link_id after sanity checks. Signed-off-by:

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. Signed-off-by:

Enter or leave IPS controlled by mac80211 before driver support HW scan. After support HW scan, driver need to control IPS before start HW scan and scan complete, but mac80211 also ask driver enter or leave IPS.
