  SubFunction [1] is a portion of the PCI device, a SF netdev has its own
dedicated queues(txq, rxq). A SF netdev supports eswitch representation
offload similar to existing PF and VF representors. A SF shares PCI
level resources with other SFs and/or with its parent PCI function.

This patch set introduces SubFunction representor support for mlx5
PMD driver.

Depends-on: series-14559 ("support SubFunction representor")
