Subject[PATCH rdma-next v1 0/7] Set flow_label and RoCEv2 UDP source port for datagram QP
From: Leon Romanovsky <>

v1: Added extra patch to reduce amount of kzalloc/kfree calls in
the HCA set capability flow.


From Mark:

This series provide flow label and UDP source port definition in RoCE v2.
Those fields are used to create entropy for network routes (ECMP), load
balancers and 802.3ad link aggregation switching that are not aware of
RoCE headers.


Leon Romanovsky (1):
net/mlx5: Refactor HCA capability set flow

Mark Zhang (6):
net/mlx5: Enable SW-defined RoCEv2 UDP source port
RDMA/core: Add hash functions to calculate RoCEv2 flowlabel and UDP
source port
RDMA/mlx5: Define RoCEv2 udp source port when set path
RDMA/cma: Initialize the flow label of CM's route path record
RDMA/cm: Set flow label of recv_wc based on primary flow label
RDMA/mlx5: Set UDP source port based on the grh.flow_label
