Hi all I have backported the commit above on the 4.14.x kernel used by Openwrt 18.06.x image family. I planned to use it with my kirkwood based router, linksys ea4500, which use mwl8k to control two radio, 2.4Ghz and 5Ghz, based on 88W8366 (see: https://wiki.openwrt.org/toh/linksys/ea4500) I built the image and loaded it on my routers (actually I have two ea4500) Unfortunately only the old 4 ch shows as supported. My question is if the modification should be enough to unlock higher non DFS channels, or if I require some other patches, or maybe new firmware. In case suggestions to troubleshoot the problem are appreciated Bye Following the "iw list" output for the 5Ghz radio Wiphy phy1 max # scan SSIDs: 4 max scan IEs length: 2261 bytes max # sched scan SSIDs: 0 max # match sets: 0 max # scan plans: 1 max scan plan interval: -1 max scan plan iterations: 0 Retry short limit: 7 Retry long limit: 4 Coverage class: 0 (up to 0m) Available Antennas: TX 0 RX 0 Supported interface modes: * managed * AP * AP/VLAN * monitor Band 2: Capabilities: 0xffe HT20/HT40 SM Power Save disabled RX Greenfield RX HT20 SGI RX HT40 SGI TX STBC RX STBC 3-streams HT Delayed Block Ack Max AMSDU length: 7935 bytes No DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: No restriction (0x00) HT TX/RX MCS rate indexes supported: 0-23, 32 Frequencies: * 5180 MHz [36] (20.0 dBm) * 5200 MHz [40] (20.0 dBm) * 5220 MHz [44] (20.0 dBm) * 5240 MHz [48] (20.0 dBm) valid interface combinations: * #{ AP } <= 8, #{ managed } <= 1, total <= 8, #channels <= 1 HT Capability overrides: * MCS: ff ff ff ff ff ff ff ff ff ff * maximum A-MSDU length * supported channel width * short GI for 40 MHz * max A-MPDU length exponent * min MPDU start spacing
