> representor
> 
> 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
