Enabling VLAN Passthrough on Marvell AQC-series NICs

Introduction¶

The author uses a Marvell AQC107-based NIC (network interface card) in their home server, which has a virtual machine used for a virtualized firewall. Unfortunately, the stock Rocky Linux Marvell AQC driver strips VLANs on bridge interfaces. This happened to the author's OPNsense virtual machine. Fortunately, it is fixable.

Prerequisites and assumptions¶

The following are the minimum requirements for using this procedure:

• A Rocky Linux server with a Marvell AQC-series NIC
• Using NetworkManager to configure networking

Disabling VLAN filtering¶

You can disable VLAN filtering with one command:

nmcli con modify enp1s0 ethtool.feature-rx-vlan-filter off

Replace enp1s0 with the name of your AQC-based NIC.

Finally, you will need to reboot your system.
