I just retried on a Packet.net m2.xlarge.x86 instance running Ubuntu 18.04
and I get:
vpp# create int rdma host-if enp94s0f1 name mlx5
create interface rdma: Device Open Failed: Bad file descriptor
On packet. I've removed the enp94s0f1 interface from the default bonded
config, and the interface is in a Down state:
3: enp94s0f1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group
default qlen 1000
link/ether 98:03:9b:30:1e:f7 brd ff:ff:ff:ff:ff:ff
The devices are ConnectX-4:
lspci | grep -i mell
5e:00.0 Ethernet controller: Mellanox Technologies MT27710 Family
[ConnectX-4 Lx]
5e:00.1 Ethernet controller: Mellanox Technologies MT27710 Family
[ConnectX-4 Lx]
