Description of problem:
When any VLAN filtering is configured on Intel X710, the configuration fails to get applied, with dmesg containing a number of following messages:
[79627.840049] i40e 0000:19:00.1: Error I40E_AQ_RC_ENOSPC adding RX filters on PF, promiscuous mode forced on

The odd part is that it happens even with a single VLAN trunk getting open, so it **should** not be a problem with lack of memory.


Version-Release number of selected component (if applicable):
RHEL 8.4
nmstate 1.0.2-14
NetworkManager in container, version 1.30.0-13.el8_4
NetworkManager on the host, version 1.30.0-10.el8_4


How reproducible:
Consistently on some PFs of the NIC. It always happens on the second one but did not happen on the third. While the second one had a wire connected, third one was disconnected.


Steps to Reproduce:
1. Get a host with Intel X710 NIC
2. Apply the following config:
    interfaces:
    - bridge:
        options:
          stp:
            enabled: false
        port:
        - name: eno2
          vlan:
            mode: trunk
            trunk-tags:
            - id: 1000
      ipv4:
        auto-dns: true
        dhcp: false
        enabled: false
      ipv6:
        enabled: false
      name: br1test
      state: up
      type: linux-bridge

Actual results:
Configuration fails, nmstate notices that requested VLANs were not applied. dmesg contains number of messages complaining about I40E_AQ_RC_ENOSPC. The number depends on how many IDs we atttemped to open.


Expected results:
We should be able to apply at least a limited numbed of trunk IDs on hardware that has offloading capability.


Additional info:

This reproduces even if vlan offloading gets disabled through ethtool:
rx-vlan-offload: off
tx-vlan-offload: off
