This patch reports .rx_free_thresh value in the .dev_infos_get ops implementation function named hns3_dev_infos_get and hns3vf_dev_infos_get. In addition, the name of the member variable of struct hns3_rx_queue is modified and comments are added to improve code readability.

|
* - exceed_limit_bd_reassem_fail
|
|
* Total number of exceeding the hardware limited bd fail which
|
|
* process a packet needed bd numbers and reassemble fail.
|
|
*
|
|
* - unsupported_tunnel_pkt_cnt
|
|
* Total number of unsupported tunnel packet. The unsupported tunnel
|
|
* type: vxlan_gpe, gtp, ipip and MPLSINUDP, MPLSINUDP is a packet
|
|
* with MPLS-in-UDP RFC 7510 header.
|
|
*
|
|
* - queue_full_cnt
|
|
* Total count which the available bd numbers in current bd queue is
|
|
* less than the bd numbers with the pkt process needed.
|
|
*
|
|
* - pkt_padding_fail_cnt
|
|
* Total count which the packet length is less than minimum packet

|
* hardware in Tx direction and fail to be appended with 0.
