This patch series provides net PMD for VVDN's NR(5G) Hi-PHY solution over
T1 telco card. These telco accelerator NIC cards are targeted for ORAN DU
systems to offload inline NR Hi-PHY (split 7.2) operations. For the DU host,
the cards typically appears as a basic NIC device. The device is based on
AMD/Xilinx's Ultrasale MPSoC and RFSoC FPGA for which the inline Hi-PHY IP
is developed by VVDN Technologies Private Limited.

- This series is an RFC and target for DPDK v22.11.
- Currently, the PMD is supported only for x86_64 host.
- Build machine used: Fedora 36 with gcc 12.1.1
- The device communicates to host over AMD/Xilinx's QDMA subsystem for
PCIe interface. Link: https://docs.xilinx.com/r/en-US/pg302-qdma
That's unfortunate, there is something else called QDMA in NXP solution:

Is this going to create a conflict against this submission? I guess both are
publicly available/known for long time.
