wifi: mt76: mt7996: Destroy active sta links in mt7996_mac_sta_remove()

2026-03-24T15:49:32Z

Similar to vif link management, postpone sta link destuction in mt7996_mac_sta_remove() introducing mt7996_mac_sta_remove_link utility routine and just disable sta link running mt7996_mac_sta_remove_links routine. This is a preliminary patch in order to support MLO link reconfiguration in MT7996 driver.

wifi: mt76: mt7996: Add mcu APIs to enable/disable vif links.

2026-03-24T15:49:32Z

Introduce mt7996_mcu_mld_reconf_stop_link and mt7996_mcu_mld_link_oper utility routines in order to communicate to the mcu fw to disable/enable a specific vif link. Please note these APIs are currently supported by the MT7996 firmware only in AP mode.

wifi: mt76: mt7996: Destroy vif active links in mt7996_remove_interface()

2026-03-24T15:49:32Z

MT7996 hw requires to remove active links from the mcu BSSINFO table destroying the interface. For this reason introduce mt7996_vif_link_destroy routine and remove active (non-offchannel) vif links running mt7996_remove_interface routine. This is a preliminary patch in order to support MLO link reconfiguration in MT7996 driver.

wifi: mt76: mt7996: Move mlink deallocation in mt7996_vif_link_remove()

2026-03-24T15:49:32Z

Destroy mt76_vif_link struct in mt7996_vif_link_remove routine and not in mt76_unassign_vif_chanctx(). This is necessary since, in order to properly support MLO link reconfiguration, we will destroy mt76_vif_link struct during AP tear-down process and not running unassign_vif_chanctx mac80211 callback. This patch does not introduce any regression since mt76_assign_vif_chanctx/mt76_unassign_vif_chanctx APIs are currently used just by MT7996 driver.

wifi: mt76: mt7996: Account active links in valid_links fields

Track active vif links in mt7996_vif_link_add and mt7996_vif_link_remove routines. This is a preliminary patch in order to remove AP MLD links from MCU configuration during AP tear-down process and to support MLO link reconfiguration in MT7996 driver.

wifi: mt76: mt7996: Rely on msta_link link_id in mt7996_vif_link_remove()

2026-03-24T15:49:32Z

Rely on msta_link link_id value in mt7996_vif_link_remove routine instead of using link_conf pointer. This assumption is correct since msta_link link_id is set to link_conf link_id value in mt7996_vif_link_add routine. Moreover, fallback to default ieee80211_bss_conf struct if the link_conf pointer in mt7996_vif_link_remove() is NULL. MT7996 hw requires to remove AP MLD links from MCU configuration during AP tear-down process (e.g. running mt7996_remove_interface()). Doing so, we can't assume link_conf pointer is always non-NULL running mt7996_vif_link_remove routine.

Release host link resources when mt7925_mac_sta_add_links() fails after partial success. msta->link[] and dev->mt76.wcid[] may already be published, so unwind the host state to avoid leaving stale links behind.

wifi: mt76: mt7925: publish msta->link after successful link add

2026-03-24T15:49:32Z

Move the msta->link[link_id] publication until after mt7925_mac_link_sta_add() succeeds. msta->link[] is RCU-visible, so publishing it before setup completes can expose a link whose add path later fails. Publish it only after success to avoid partially initialized link state becoming visible.
