From: Leon Romanovsky
Date: Mon May 04 2020 - 01:19:48 EST


From: Leon Romanovsky <leonro@xxxxxxxxxxxx>

Changelog:
v3: Rebased on latest rdma-nex, which includes HCA set capability patch
and LAG code and this is why new patch from Maor was added.
v2: https://lore.kernel.org/linux-rdma/20200413133703.932731-1-leon@xxxxxxxxxx
Dropped patch "RDMA/cm: Set flow label of recv_wc based on primary
flow label", because it violates IBTA 13.5.4.3/13.5.4.4 sections.
v1: https://lore.kernel.org/lkml/20200322093031.918447-1-leon@xxxxxxxxxx
Added extra patch to reduce amount of kzalloc/kfree calls in
the HCA set capability flow.
v0: https://lore.kernel.org/linux-rdma/20200318095300.45574-1-leon@xxxxxxxxxx

>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.

Thanks.

Maor Gottlieb (1):
RDMA/core: Consider flow label when building skb

Mark Zhang (4):
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/mlx5: Set UDP source port based on the grh.flow_label
