Subject[net-next v3 05/14] octeontx2-pf: cn10k: Initialise NIX context
Date
On CN10K platform NIX RQ and SQ context structure got changed.
This patch uses new mbox message "NIX_CN10K_AQ_ENQ" for NIX
context initialization on CN10K platform.

This patch also updates the nix_rx_parse_s and nix_sqe_sg_s
structures to add packet steering bit feilds.
