Technical Description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: Fix peer devlink set for SF representor devlink port

The cited patch change register devlink flow, and neglect to reflect

the changes for peer devlink set logic. Peer devlink set is

triggering a call trace if done after devl_register.[1]

Hence, align peer devlink set logic with register devlink flow.
