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.
Wow, great! Where can I get the latest version of your driver for fresh
RELENG_6? I'm willing to test it! I could live w/o TSO support and RX checksum
offload; while hardware VLAN tagging is desirable feature. Does your driver
support software VLAN tagging currently?

You can see lots of witness warnings. Unloading the driver module or

using Jumboframe may panic your system.
Thanks for the information!
