Hi Adrien/Nelio,
I am trying to find out what kernel changes need to be back-ported for
Linux kernel 4.12 from 4.14. We have rdma-core 16 and dpdk 17.11
already. Wondering if that back port is possible at all.
It would be great if I get some specific kernel commits(when possible)
that are mandatory for dpdk+mlx support.
Regards
Nirmoy

While I have several mandatory patches in mind for mlx4 that were pushed
between 4.14 and 4.15, I'm not familiar enough with what happened on the
Linux side to compile a complete list for 4.12. The useful info here is you
should target 4.15 for proper mlx4 support, not 4.14.
Adding Shahaf who may know the right people to request such a list from.
