I've tried but max MTU is 2048 on one device: $ sudo ibv_devinfo hca_id: mthca0 transport: InfiniBand (0) fw_ver: 4.7.600 node_guid: 0008:f104:0398:14cc sys_image_guid: 0008:f104:0398:14cf vendor_id: 0x08f1 vendor_part_id: 25208 hw_ver: 0xA0 board_id: VLT0040010001 phys_port_cnt: 2 port: 1 state: PORT_ACTIVE (4) max_mtu: 2048 (4) active_mtu: 2048 (4) sm_lid: 1 port_lid: 2 port_lmc: 0x00 link_layer: InfiniBand any workaround? Maybe a firmware update ? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
