[PATCH rdma v1 0/2] Add ZTE DingHai Ethernet Protocol Driver for RDMA

[zhang.yanze]

From: Yanze Zhang <zhang.yanze@xxxxxxxxxx>

This series adds initial RoCEv2 support for the ZTE ZXDH RNIC,
a PCIe Gen5 adapter.

The driver implements core IB verbs (QP/CQ/MR/SRQ/AH) with async CQP
command path and DCQCN congestion control, using the auxiliary bus
framework following hns/bnxt_re patterns. It does not include Ethernet
network data plane support. Perftest shows ~395 Gb/s write bandwidth at
4KB message size over RoCEv2 RC/UD QPs.
