I have been trying to use the netvsc PMD driver lately and face an issue
with the RSS flag for UDP.
I figured that this is because the PMD does not handle NDIS_HASH_UDP_IPV4,
so I am planning at trying to submit a change to the PMD, however I am
unsure about the value of the UDP constant. I found on
that it should be 0x00004000.
Would someone have some proper knowledge about this specific setting?

And after having used that change locally, I am now facing some issues with
the mlx4 PMD used under the hood of netvsc. My memory allocation makes my
buffers exist at a different location than my memory pool and this creates
an issue:
net_mlx4: port 0 unable to find virtually contiguous chunk for address
Did someone already tried to use some custom memory management with the mlx
