Description:
The /sys/devices/platform/HISI04Bx:00/chipX/ directory
contains read-only attributes exposing some summarization
information of all HCCS ports under a specified chip.
The X in 'chipX' indicates the Xth chip on platform.
There are following attributes in this directory:
================= ==== =========================================
all_linked: (RO) if all enabled ports on this chip are
linked (bool).
linked_full_lane: (RO) if all linked ports on this chip are full
lane (bool).
crc_err_cnt: (RO) total CRC err count for all ports on this
chip.

The Y in 'dieY' indicates the hardware id of the die on chip who
has chip id X.
There are following attributes in this directory:

Description:
The /sys/devices/platform/HISI04Bx/chipX/dieX/hccsN/ directory
contains read-only attributes exposing information about
a HCCS port. The N value in 'hccsN' indicates this port id.
The X in 'chipX' indicates the ID of the chip to which the
HCCS port belongs. For example, X ranges from to 'n - 1' if the
chip number on platform is n.
The Y in 'dieY' indicates the hardware id of the die to which
the hccs port belongs.
Note: type, lane_mode and enable are fixed attributes on running
platform.
The HCCS port have the following attributes:
============= ==== =============================================
type: (RO) port type (string), e.g. HCCS-v1 -> H32
lane_mode: (RO) the lane mode of this port (string), e.g. x8
enable: (RO) indicate if this port is enabled (bool).
cur_lane_num: (RO) current lane number of this port.
link_fsm: (RO) link finite state machine of this port.
lane_mask: (RO) current lane mask of this port, every bit
indicates a lane.
crc_err_cnt: (RO) CRC err count on this port.
