Hi guys, I'm seeing a problem when I work on the wireless mesh between two linux devices. The root node has 3.18 kernel while the next hop station runs 2.6.37 kernel. I found the mpath->sn value is incorrect most of the time on the device having 2.6.37 kernel. After examining the code, in function hwmp_route_info_get [mesh_hwmp.c], after mesh_path_lookup, the sequence number (i.e, mpath->sn) is incorrect. For instance, I see mpath->sn having value 0x30950000. It should be 0x9530, while the orig_sn is having value 0x9531. This results in the last hop metric to become zero in function mesh_rx_path_sel_frame and hwmp_preq_frame_process doesn't get called. Is this a known problem? Can anyone provide suggestions to debug further?
