[PATCH v3 0/4] Generate UDP src port with flow label or lqpn/rqpn

[yanjun.zhu@linux.dev]

From: Zhu Yanjun <yanjun.zhu@linux.dev>

Follow the advice from Leon Romanovsky, rdma_get_udp_sport is moved to
ib_verbs.h. several drivers generate udp source port with this function.

---
v2->v3:Because in-subnet communications, GRH is optional. Without thei
       randomization for src_port done in rxe_qp_init_req, udp source
       port will be 0xC000 in that case.
v1->v2:Remove the local variables in commits "RDMA/irdma: Make the source
       udp port vary" and "RDMA/rxe: Use the standard method to produce
       udp source port". A new commit is added to remove the redundant
       randomization for UDP source port in RXE.

Zhu Yanjun (4):
  RDMA/core: Calculate UDP source port based on flow label or lqpn/rqpn
  RDMA/hns: Replace get_udp_sport with rdma_get_udp_sport
  RDMA/irdma: Make the source udp port vary
  RDMA/rxe: Use the standard method to produce udp source port
