Hey

I just installed a new quad nic Intel based card in my Proxmox server.

It works just fine but I am a bit puzzled to see eight new cards inside Proxmox. I can only see the expected four when running `ip a` from console.

Can anyone explain why there are four extra cards inside Proxmox?

This is from `ip a`, the new card have the nics labelled enp5s0f0, enp5s0f1, enp6s0f0, and enp6s0f1. I have redacted the lines with ip, and mac addresses.

Code:
2: enp11s0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP group default qlen 1000
3: enp12s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
4: enp5s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
5: enp15s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr0 state UP group default qlen 1000
6: enp16s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr2 state UP group default qlen 1000
7: enp17s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
8: enp5s0f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
9: enp18s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
10: enp20s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr3 state UP group default qlen 1000
11: enp6s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
12: enp6s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

This is from inside Proxmox. Here I also see the cards `enp5s0p0`, `enp5s0p1`, `enp6s0p0`, `enp6s0p1`.

Fun thing the cards seen with `ip a` don't have auto activate, I can't enable it either. It also doesn't seem necessary because everything without it. I don't have any problems at all, except that I don't understand why the extra cards are visible inside Proxmox but I can't see them anywhere else in the system.

And look which cards that are marked as `active`, it's the opposite from the auto starting cards. :)
