How to interact with kernel for FreeBSD

[陳健新]

Hi all,

I am porting the DPDK program to support FreeBSD, the original program uses
the virtio_user to communicate with the kernel. However, when running on
FreeBSD, the EAL failed with error message as below:

EAL: failed to parse device "vdev:virtio_user0"
EAL: Failed to attach device on primary process

Then I tried with the tap dev but it also failed:

EAL: failed to parse device "vdev:net_tap0"
EAL: Failed to attach device on primary process

Is there a way to send/receive packet to the kernel on FreeBSD?
Please help. Thank you very much.

Best regards,
James
