From 7274d6cc43bc87d90f96534777ff3fc1f0b3a639 Mon Sep 17 00:00:00 2001 From: Sean Wang Date: Sat, 13 Jun 2026 17:51:43 -0500 Subject: [PATCH] wifi: mt76: mt7927: set band index for sniffer mode Use the active channel context to select the SNIFFER command band index on MT7927, and fall back to the PHY chandef when no channel context is available. Also pass the same band index to the sniffer channel configuration. This keeps monitor setup on the correct band, especially when multiple PHY band contexts are present.
