The RDMA driver supports the following features:
Supports Huawei SP600 series NICs;
Supports RoCEv2;
Supports RoCE UC, RC, and UD local switching;
Supports RoCE MR, PD, CQ, QoS, QP, and SRQ management;
Supports RoCE congestion control;
Supports RoCE Bond;
Supports RoCE FLR;
Supports RoCE entry specifications;
Supports RoCE error detection and reporting;

CQM components:

==========



The CQM module organizes the memory in the large system in a format (CLA table)

and allocates the memory to the chip (BAT table). The chip can use the memory in

the large system to save context information and queue information (SCQ\SRQ).

(cqm_bat_cla.c, cqm_bat_cla.h, cqm_bitmap_table.c, cqm_bitmap_table.h)



When a packet is transmitted from the PCIe link, the chip parses the 5-tuple

such as sid, did, and hostid. Fill the parsed data in the queue

(in the form of scqe). In this way, the driver can directly obtain data from the

queue (through MPDK polling) and then process the data. In this way, the

uninstallation is implemented.
