====================
mlx5-updates-2021-01-05

SW steering, Refactor to have a device specific STE layer below dr_ste

This series introduces some improvements and refactoring by adding a new layer
below dr_ste to allow support for different devices format.

It adds a struct of device specific callbacks for STE layer below dr_ste.
Each device will implement its HW-specific function, and a common logic
from the DR code will access these functions through the new ste_ctx API.

Connect-X5-style steering format is called STE_v0.
In the next patch series we bring the Connect-X6-style format - STE_v1.
