[dpdk-dev] [PATCH v5 0/9] net/mlx5: support SubFunction representor

[Xueming Li]

SubFunction [1] is a portion of the PCI device, a SF netdev has its own
dedicated queues(txq, rxq). A SF netdev supports E-Switch 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.

Version history:
 RFC:
 	initial version [2]
 V2:
    - support bonding representor probe with new pf#vf# devargs
    - adapt EAL api V2 [3] changes
    - update document
 V3:
    - support list of representor PF section for bonding device:
      example: representor=pf[0,1]vf[0-3]
    - add bonding information to shared PMD data
    - fix setting VF MAC through representor
    - fix bonding xstats, sum xstats from PF members.
 V4:
    - combine unexpected patch, thanks Slava
 V5:
    - support new ethdev ops api to return representor info
    - new api to encode and decode representor ID
    - new patch to allow BF2 HPF(-1) probe with sf-1
