[dpdk-dev] [PATCH 00/12] net/mlx5: add bonding configuration support

[Matan Azrad]

From: Viacheslav Ovsiienko
> Multiport Mellanox NICs may support the bonding configurations internally.
> Let's suppose there is ConnectX-5 NIC with two physical ports, on the host it
> presents two PCI physical functions:
> 
> - PF0, say with PCI address 0000:82:00.0 and net interface ens1f0
> - PF1, say with PCI address 0000:82:00.1 and net interface ens1f1
> 
> Also, let's suppose SR-IOV feature is enabled, swithdev mode is engaged,
> and there is some set virtual PCI functions and their representor interfaces.
> The physical interfaces may be combined into single bond interface,
> supported by NIC HW/FW means directly with standard script:
> 
>   modprobe bonding miimon=100 mode=4  # 100 ms link check interval, mode
> - LACP
>   ip link set ens3f0 master bond0
>   ip link set ens3f0 master bond1
> 
> The dedicated Infiniband devices for single ports is destroyed, the new
> multiport Infiniband device is created for bond interface and all representors
> for both PFs. The unified E-Switch is created either, and all representor ports
> belong to the same unified switch domain.
> 
> To use the created bond interface with DPDK application both slave PCI
> devices must be specified (in whitelist, if any):
> 
>   -w 82:00.0,representor=[0-4]
>   -w 82:00.1,representor=[0-7]
> 
> Representor enumerations follows the VF enumerations in the same way as
> for single device. The two PCI devices will be probed, but eth ports for only
> one master device and for all representors will be created.
> This ports may reference to different rte_pci_dev but share the same switch
> domain ID.
> 
> The extra devargs specifying configurations must be compatible (otherwise
> error on probing will be arisen). For example, it is not allowed to specify
> different values of dv_flow_en parameter for different PCI devices.
