Ok so I couldn't figure out the right way to google this and it is kinda maddening...

Fresh install of 7.1, on a SuperMicro server with 4 eth ports and I have both EN and ETH interfaces. WHY?! No extra nic cards in the system so why am I seeing both? I have been having issues with the system rebooting without any internet connection (testing the hard set mac on the vmbro as I know that's a known issue) but it makes me think maybe something else is going on and this dual EN and ETH could be the reason...

Code:
root@prox:~# ip -c link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: eno1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000

    altname enp6s0f0

3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

    altname enp6s0f1

4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc mq master bond0 state DOWN mode DEFAULT group default qlen 1000

    altname enp6s0f2

5: eth3: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc mq master bond0 state DOWN mode DEFAULT group default qlen 1000

    altname enp6s0f3

6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master vmbr0 state UP mode DEFAULT group default qlen 1000

7: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000

24: tap112i0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master fwbr112i0 state UNKNOWN mode DEFAULT group default qlen 1000

25: fwbr112i0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000

26: fwpr112p0@fwln112i0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master vmbr0 state UP mode DEFAULT group default qlen 1000

27: fwln112i0@fwpr112p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master fwbr112i0 state UP mode DEFAULT group default qlen 1000


Code:
root@prox:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eno1 inet manual

iface eth1 inet manual

iface eth2 inet manual

iface eth3 inet manual

auto bond0
iface bond0 inet static
        bond-slaves eno1 eth1 eth2 eth3
        bond-miimon 100
        bond-mode balance-alb
        bond-xmit-hash-policy layer2+3

auto vmbr0
iface vmbr0 inet static
        address XXX/24
        gateway XXX
        hwaddress XX:XX:XX:XX:XX:XX
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0

Any input here would be appreciated as I feel like I am missing something simple, also inb4 someone links me to Naming Conventions in https://pve.proxmox.com/wiki/Network_Configuration
 
I'm bumping this again because I just don't understand and it's driving me insane. Please any exp as to why a 4 NIC superMicro mobo would label 3 ports one way and 1 port another, esp based off the Network Config Proxmox exp
