Michael Guralnik says:

====================
This series handles IPoIB child interface creation with setting
interface's HW address.

In current implementation, lladdr requested by user is ignored and
overwritten. Child interface gets the same GID as the parent interface and
a QP number which is assigned by the underlying drivers.

In this series we fix this behavior so that user's requested address is
assigned to the newly created interface.

As specific QP number request is not supported for all vendors, QP number
requested by user will still be overwritten when this is not supported.

Behavior of creation of child interfaces through the sysfs mechanism or
without specifying a requested address, stays the same.
====================

Based on the mlx5-next branch at
      git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies.

* branch 'mlx5_ipoib_qpn':
  RDMA/ipoib: Handle user-supplied address when creating child
  net/mlx5: Enable QP number request when creating IPoIB underlay QP
