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
