From: Mark Bloch <markb@mellanox.com>
 =========
 Add IB representor when in switchdev mode
 
 The following series adds support for an IB (RAW Ethernet only) device
 representor which is created when the user switches to switchdev mode.
 
 Today when switching to switchdev mode the only representors which are
 created are net devices. Each netdev is a representor of a virtual
 function and any data sent via the representor is received on the virtual
 function, and any data sent via the virtual function is received by the
 representor.
 
 For the mlx5 driver the main use of this functionality is to be able to
 use Open vSwitch on the hypervisor in order to manage/control traffic
 from/to the virtual functions. Open vSwitch can also work with  DPDK
 devices and not just net devices, this series exposes an IB device, which
 Mellanox PMD driver uses, which then can be used by Open vSwitch DPDK.
 
 An IB device representor exposes only RAW Ethernet QP capabilities and
 the ability to create flow rules to direct traffic to its RX queues. The
 state of the IB device (ACTIVE/DOWN etc..) is based on the state of the
 corresponding net device representor. No other RDMA/RoCE functionality is
 currently supported and no GID table is exposed.
