This removes the dependency on specific Mellanox OFED libraries by using the upstream rdma-core and linux upstream community code. Both rdma-core upstream and Mellanox OFED are Linux user-space packages: 1. Rdma-core is Linux upstream user-space package.(Generic) 2. Mellanox OFED is Mellanox's Linux user-space package.(Proprietary) The difference between the two are the APIs towards the kernel. Support for x86-32 is removed due to issues in rdma-core library. ICC compilation will be supported as soon as the following patch is integrated in rdma-core: https://marc.info/?l=linux-rdma&m=150643474705690&w=2 Signed-off-by: Shachar Beiser <shacharbe@mellanox.com> Signed-off-by: Nelio Laranjeiro <nelio.laranjeiro@6wind.com>
