[PATCH 04/15] wifi: mt76: mt7925: report only 2.4 GHz NAN supported band
From: Sean Wang <sean.wang@kernel.org>
Date: 2026-08-24 19:53:10
Also in:
linux-mediatek
Subsystem:
mediatek mt76 wireless lan driver, the rest · Maintainers:
Felix Fietkau, Lorenzo Bianconi, Ryder Lee, Linus Torvalds
From: Stella Liu <redacted>
The firmware only checks the 2.4 GHz bit of the local device capability
supported_bands field, so set it directly and drop the unused helper.
Fixes: 0f3605e4f8de ("wifi: mt76: mt7925: wire up NAN operations")
