rdma: set correct CQE flags
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. Type: fix Signed-off-by: Jieqiang Wang <jieqiang.wang@arm.com> Change-Id: I9b578ca5cbd8cd93a577aa83131e31c79f60430e
