From: Arkadiusz Kubalewski <arkadiusz.kubalew...@intel.com>
New trace indicates that the XDP program was loaded.
The trace has a note that in case of using XDP_REDIRECT,
number of queues on both interfaces shall be the same.
This is required for optimal performance of XDP_REDIRECT,
if interface used for TX has lower number of queues than
a RX interface, the packets may be dropped (depending on
RSS queue assignment).
