[PATCH 02/19] net/cnxk: new tree for SDP interface

[Nithin Dabilpuram]

From: Satha Rao <skotesh...@marvell.com>

Create a new default tree for the SDP interface if more than one TX
queue is requested. This helps to backpressure each queue independently
when they are created with separate channels.
