Add default RSS key for CNXK platforms. CNXK platform uses 48 bytes long
key for hash calculations and a default RETA size of 64.
Example:
~$ usertools/dpdk-rss-flows.py 8 28.0.0.0/24 40.0.0.0/24 -k cnxk
SRC_IP DST_IP QUEUE
28.0.0.1 40.0.0.1 7
28.0.0.1 40.0.0.2 2
28.0.0.1 40.0.0.3 4
28.0.0.1 40.0.0.7 1
28.0.0.1 40.0.0.8 3
28.0.0.1 40.0.0.9 5
