-----------------------------------------------------------------------

Hi,

This is comprehensive part of kernel series posted earlier. The kernel part is not accepted yet, so first patch will have different commit message with different commit SHA1. This is why it is marked as RFC.

An example:

[leonro@server /]$ lspci |grep -i Ether
00:08.0 Ethernet controller: Red Hat, Inc. Virtio network device
00:09.0 Ethernet controller: Mellanox Technologies MT27700 Family [ConnectX-4] [leonro@server /]$ sudo rdma dev
1: mlx5_0: node_type ca fw 3.8.9999 node_guid 5254:00c0:fe12:3455 sys_image_guid 5254:00c0:fe12:3455 [leonro@server /]$ sudo rdma dev set mlx5_0 name hfi1_0
[leonro@server /]$ sudo rdma dev
1: hfi1_0: node_type ca fw 3.8.9999 node_guid 5254:00c0:fe12:3455 sys_image_guid 5254:00c0:fe12:3455

Thanks
