Hi Shachar,
I can finally able to compile this via rdma-core v15 (Thanks to Nelio),
since I don't have Mellanox OFED 4.2
1- Shared library build fails. mlx5 driver now depends on libmlx5.so,
this dependency should be added [1], otherwise giving build error [2].
2- 32bit build broken, this is because rdma-core 32bit missing.
a) Is rdma-core supports 32bit?
b) Is mlx5 supports 32bit?
3- I am getting ICC warning from rdma-core header [3], same warning many
times. Would you mind disabling that warning for mlx5 [4] ?
