Subject: [PATCH rdma-next] RDMA/nldev: Skip counter if port doesn't match
Date: Sun, 20 Oct 2019 09:28:00 +0300 [thread overview]
Message-ID: <20191020062800.8065-1-leon@kernel.org> (raw)
From: Mark Zhang <markz@mellanox.com>
Counter resource should return -EAGAIN if it was requested for other
part. Such situation can occur in multi-port systems.
Fixes: c4ffee7c9bdb ("RDMA/netlink: Implement counter dumpit calback")
