When doing a "iw dev wls1 scan" on a parallel running managed interface on the same phy, the packet capture will contain beacons and probe responses from the scan though. Can anyone confirm that? mt76 (https://github.com/openwrt/mt76/commits/master): commit 6fad970893dd26ef6e6c8344b958344254f6362a (HEAD -> master, origin/master, origin/HEAD) Kernel: 5.16.0-rc2-next-20211124+ WM Firmware Version: ____010000, Build Time: 20211014150922 Steps to reproduce: sudo iw dev wls1 del sudo iw phy phy0 interface add mon0 type monitor sudo ip link set dev mon0 up sudo iw dev mon0 set freq 6115 sudo tcpdump -i mon0 -w 6g-capture.pcap Kinds regards, Jan _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek
