See the following [03:00.1 and 03:00.1]:

I can only see the second 10-Gigbit NIC when I use the ip command , or is it the eno1? [expecting enp3s0f0]:

Well that is odd, the second 10Gb nic is that eno1 (used ethtool to figure out it is a 10G nic)... why is that?

where do these names come from?

hi,

I can only see the second 10-Gigbit NIC when I use the ip command , or is it the eno1? [expecting enp3s0f0]:
yes it seems to be eno1

here your two bridge interfaces:
Code:
8: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether ac:16:2d:93:6f:0c brd ff:ff:ff:ff:ff:ff
9: vmbr2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether 3c:ec:ef:1b:c6:dd brd ff:ff:ff:ff:ff:ff

note the MAC addresses. and the respective interfaces:
Code:
2: enp130s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master vmbr0 state UP mode DEFAULT group default qlen 1000
    link/ether ac:16:2d:93:6f:0c brd ff:ff:ff:ff:ff:ff
6: eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 3c:ec:ef:1b:c6:dc brd ff:ff:ff:ff:ff:ff

where do these names come from
can you show us your network configuration from /etc/network/interfaces ?
