All representors belonging to the > same E-Switch are created on the basis of the single PCI function and with > current implementation each representor has its own dedicated Infiniband > device and operates within its own Infiniband context. It is proposed to > provide representors as ports of the single Infiniband device and operate on > the shared Infiniband context saving various resources. This patch introduces > appropriate structures. > > Also the functions to allocate and free shared IB context for multiport are > added. The IB device context, Protection Domain, device attributes, > Infiniband names are going to be relocated to the shared structure from the > device private one. > mlx5_dev_spawn() is updated to support shared context. > > Signed-off-by: Viacheslav Ovsiienko <viachesl...@mellanox.com>
