> 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
