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

From: Leon Romanovsky <[email protected]>

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

Yes, you are right.

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

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

Thank you.
