Sub-Function [1] is a portion of the PCI device, a SF netdev has its own
dedicated queues(txq, rxq). A SF shares PCI level resources with other
SFs and/or with its parent PCI function. Auxiliary bus is the
fundamental of SF.
This patch set introduces Sub-Function support for mlx5 PMD driver
including class net, regex, vdpa and compress.
