[v1] Add gratuitous ARP support to RDMA-CM

[PATCH rdma-next 0/2] Add gratuitous ARP support to RDMA-CM

Posted by Leon Romanovsky 4 years, 2 months ago

From: Leon Romanovsky <leonro@nvidia.com>

In this series, Patrisious adds gratuitous ARP support to RDMA-CM, in
order to speed up migration failover from one node to another.

Thanks

Patrisious Haddad (2):
  RDMA/core: Add an rb_tree that stores cm_ids sorted by ifindex and
    remote IP
  RDMA/core: Add a netevent notifier to cma

Hi Leon,

Are these the 2 patches that are supposed to fix: [Bug 214523] New:
RDMA Mellanox RoCE drivers are unresponsive to ARP updates during a
reconnect?

I could be wrong but I don't think they made it into the 5.18 pull, correct?

Thank you.
