I'm working on it. Unlike OpenBSD/NetBSD msk(4) my code is based on
sk(4) and myk(4) from Marvell. I've managed to send packets with new
driver but it needs more testing and codes to support hardware
features(VLAN tagging, TSO support, RX checksum offload etc). I can't
sure TSO support could be done due to lack of documentation.

You can see lots of witness warnings. Unloading the driver module or
using Jumboframe may panic your system.
