Hi,
I'm trying to use ConnectX-5 NIC interfaces in VPP (20.09) application running
on a x86 host (Ubuntu 18.04), but unable to find this interface in VPP.
Do we need to create rdma interface to use mlx5 NIC interfaces? Or is there any
other way to use this?
Below are configuration/NIC and other relevant details:
vpp# sh interface
Name Idx State MTU (L3/IP4/IP6/MPLS)
Counter Count
local0 0 down 0/0/0/0
VPP startup configuration:
dpdk {
dev 0000:d9:00.0 {
name eth0
}
}
plugins {
plugin default { enable }
plugin dpdk_plugin.so {enable }
}
NIC driver status:
Network devices using kernel driver
