Hello! I have one issue and I have no solution for now.
Proxmox version.

pve-manager/8.4.0/ec58e45e1bcdf2ac (running kernel: 6.8.12-9-pve)

I have this kind of nics
19:00.0 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57840 NetXtreme II 10 Gigabit Ethernet [14e4:16a1] (rev 11)
19:00.1 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57840 NetXtreme II 10 Gigabit Ethernet [14e4:16a1] (rev 11)
19:00.2 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57840 NetXtreme II 10 Gigabit Ethernet [14e4:16a1] (rev 11)
19:00.3 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57840 NetXtreme II 10 Gigabit Ethernet [14e4:16a1] (rev 11)

And this version of driver:

driver: bnx2x
version: 6.8.12-9-pve
firmware-version: FFV16.20.00 bc 7.14.18
expansion-rom-version:
bus-info: 0000:19:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes


I have configured a nfs share for storage in nfs.
This is my network config:

auto eno1

iface eno1 inet manual
auto eno1.807

iface eno1.807 inet static
address x.x.x.x/24

.
But everytime when I try to make basic actions, like cloning one virtual machine, the interface is reporting errors.

2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:0e:1e:ec:6f:d0 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped missed mcast
86306376470 35548258 23225 5 0 0
TX: bytes packets errors dropped carrier collsns
86106817946 32273939 0 0 0 0
altname enp25s0f0

Do you have a solution for this?
 
You are missing basic parts of your config file. Try this. I have assumed you want to put your management interface on VLAN 807. If that's not correct, please let me know.

Code: 
auto lo
iface lo inet loopback

# Physical interface
auto eno1
iface eno1 inet manual

# VLAN-aware bridge for Proxmox networking
auto vmbr0
iface vmbr0 inet manual
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes

# Management interface on VLAN 807
auto vmbr0.807
iface vmbr0.807 inet static
    address 192.168.807.10/24   # adjust to your mgmt subnet
    gateway 192.168.807.1          # adjust to your mgmt gateway

No, I just sent a part of the config only for nfs. All the other stuff is working. I want to use one nic for mounting nfs. Migration is working, everything. When I want to use that nic to mount a nfs, I can mount it, I can clone stuff, but is giving me errors, even is the clone process is working.
 
Are you trying to mount an NFS on the Proxmox host, or ona VM? I have never had to manipulate my /etc/network/interfaces file to set up NFS
