2022-10-25rdma: set correct CQE flagsJieqiang Wang1-6/+6
CQE flags located in bits 16-31 at offset 0x1c should be defined as actual numbers instead of indexes. Besides, L3 header type for IPv4 is 10(2 in decimal) and for IPv6 is 01(1 in decimal) according to CQE entry fields description of page 120 in Mellanox Programmer Reference Manual. (https://network.nvidia.com/files/doc-2020/ethernet-adapters-programming-manual.pdf) Fixing this issue will lead to correct CQE flags printing for rdma-input node when buffer trace is enabled.

2020-10-24rdma: implement striding rq for multiseg rxMohammed Hawari1-3/+19
This change leverages the striding RQ feature of ConnectX-5 adapters to support chained buffers on the RX path. In Striding RQ mode, WQE are SG lists of data segments, each mapped to a vlib_buffer. When a packet is received, it can consume one or multiple data segments belonging to the WQE, without wasting the whole WQE.
