The N value in 'hccsN' indicates this port id. 62 The X in 'chipX' indicates the ID of the chip to which the 63 HCCS port belongs. For example, X ranges from to 'n - 1' if the 64 chip number on platform is n. 65 The Y in 'dieY' indicates the hardware id of the die to which 66 the hccs port belongs. 67 Note: type, lane_mode and enable are fixed attributes on running 68 platform. 69 70 The HCCS port have the following attributes: 71 72 ============= ==== ============================================= 73 type: (RO) port type (string), e.g. HCCS-v1 -> H32 74 lane_mode: (RO) the lane mode of this port (string), e.g. x8 75 enable: (RO) indicate if this port is enabled (bool). 76 cur_lane_num: (RO) current lane number of this port. 77 link_fsm: (RO) link finite state machine of this port. 78 lane_mask: (RO) current lane mask of this port, every bit 79 indicates a lane. 80 crc_err_cnt: (RO) CRC err count on this port. 81 ============= ==== =============================================
