Add an ICE_RX_FLAG_MULTIDEV flag to Rx ring. If it is set try to find correct port representor. Do it based on src_vsi value stored in flex descriptor. Ids of representor pointers stored in xarray are equal to corresponding src_vsi value. Thanks to that we can directly get correct representor if we have src_vsi value. Set multidev flag during ring configuration. If the mode is switchdev, change the ring descriptor to the one that contains src_vsi value. PF netdev should be reconfigured, do it by calling ice_down() and ice_up() if the netdev was up before configuring switchdev.
