Subject: [PATCH 00/19] wifi: mt76: mt7925: fix up MLO link lifetime and error handling
Date: Fri, 6 Mar 2026 17:22:19 -0600 [thread overview]
Message-ID: <20260306232238.2039675-1-sean.wang@kernel.org> (raw)
From: Sean Wang <sean.wang@mediatek.com>
Hi,
This series fix up MLO link STA lifetime and error handling in mt7925.
The current add path may expose partially initialized links and does
not reliably release host resources when firmware commands fail (e.g.
MCU timeouts). In addition, several helpers internally look up mlink,
creating implicit dependencies on driver state and making the code
harder to reason about and maintain.
Switch link STA handling to RCU lifetime, align WCID publish/teardown
ordering, pass mlink explicitly to helpers, and add host-side unwind
logic to release resources when link add fails.
