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 https://microsoft.github.io/windows-docs-rs/doc/windows/Win32/NetworkManagement/Ndis/constant.NDIS_HASH_UDP_IPV4.html 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 pmd? Thanks, Sylvain [-- Attachment #2: Type: text/html, Size: 1147 bytes --]
