That looks like a bug, the bits in ndis.h came from Linux and FreeBSD
driver includes. Looks like the UDP stuff isn't defined there.
The MANA driver does have bits defined for UDP for NDIS, but the
bits are different. I suspect that maybe it uses a different NDIS
version.
Long maybe able to look into this more.
Note: I don't work for Microsoft anymore, and don't have free/easy way
to use/test netvsc PMD anymore.
Also, lack of access to Windows/Hyper-V source makes things more difficult.
