Bah. Yeah. Should have just used them directly. I didn't add ETH_MAX_MTU
until after doing the virtio_net changes, so I missed that.

[PATCH] virtio-net: Read MAC only after initializing MSI-X
The MAC of a virtio-net device is located at the first field of the device
specific header. This header is located at offset 20 if the device doesn't
support MSI-X or offset 24 if it does.
Current code in virtnet_probe() used to probe the MAC before checking for
MSI-X, which means that the read was always made from offset 20 regardless
of whether MSI-X in enabled or not.
This patch moves the MAC probe to after the detection of whether MSI-X is
enabled. This way the MAC will be read from offset 24 if the device...

[PATCH v2 0/1] virtio_net: vdpa: update MAC address when it is generated by virtio-net
...a random one without notifying the device.
The consequence, in the case of mlx5_vdpa, is the internal routing
tables of the device are not updated and this can block the
communication between two namespaces.
To fix this problem, use virtnet_send_command(VIRTIO_NET_CTRL_MAC)
to set the address from virtnet_probe() when the MAC address is
not provided by the device.
v2:
- remove vdpa_sim related fixes
- check virtio_has_feature(vdev, VIRTIO_NET_F_MAC) rather than
addr_assign_type
