Hi,
I recently started to try to use MLX MT27520 ConnectX-3 Pro cards
(2x40Gbps) with VPP. The card itself should be supported in DPDK with
the mlx4 PMD, but I had to add a small patch to vpp-dpdk to allow 1007
as device ID.
Besides that, I'm not able to start VPP because it crashes with
"vlib_register_node:383: more than one node named
`FiftySixGigabitEthernet7/0/0-tx'".
I've checked the Bus info for this card and it seems that both ports are
mapped to the same PCI Function.
------------%<------------
# lshw -c network -numeric -businfo
Bus info Device Class Description
=======================================================
pci@0000:07:00.0 ens2 network MT27520 Family [ConnectX-3
Pro] [15B3:1007]
pci@0000:07:00.0 ens2d1 network Ethernet interface
------------%<------------
I haven't been able to find out if there's a way to "hack" the 2nd port
to another PCI Function with mlxlink, but it seems that these cards are
too old for mlxlink.
Has anyone faced a similar or the same issue and found a solution for that?
For those who ask: I'm running VPP 23.02-rc2~0-gbe1b84421.
Cheers,
Tom
