net/mlx5: Add SHAMPO caps, HW bits and enumerations
This commit adds SHAMPO bit to hca_cap and SHAMPO capabilities structure,
SHAMPO related HW spec hardware fields and enumerations.
SHAMPO stands for: split headers and merge payload offload.
SHAMPO new fields:
WQ:
- headers_mkey: mkey that represents the headers buffer, where the packets
headers will be written by the HW.
- shampo_enable: flag to verify if the WQ supports SHAMPO feature.
- log_reservation_size: the log of the reservation size where the data of
the packet will be written by the HW.
- log_max_num_of_packets_per_reservation: log of the maximum number of
packets that can be written to the same reservation.
- log_headers_entry_size: log of the header entry size of the headers buffer.
- log_headers_buffer_entry_num: log of the entries number of the headers buffer.
RQ:
- shampo_no_match_alignment_granularity: the HW alignment granularity
in case the received packet doesn't match the current session.
- shampo_match_criteria_type: the type of match criteria.
- reservation_timeout: the maximum time that the HW will hold the
reservation.
mlx5_ifc_shampo_cap_bits, the capabilities of the SHAMPO feature:
- shampo_log_max_reservation_size: the maximum allowed value of the field
WQ.log_reservation_size.
- log_reservation_size: the minimum allowed value of the field
WQ.log_reservation_size.
- shampo_min_mss_size: the minimum payload size of packet that can open
a new session or be merged to a session.
- shampo_max_log_headers_entry_size: the maximum allowed value of the field
WQ.log_headers_entry_size
