Bug Description
Mellanox ConnectX architecture is: mlx4_core is the lower level PCI driver which register on the PCI id, and protocol specific drivers are depended on it: mlx4_en - for Ethernet and mlx4_ib for Infiniband. NIC could have multiple ports which can change their type dynamically. We use the request_module() call to load the relevant protocol driver when needed: on loading time or at port type change event.
The mlx4_core and mlx5_core modules are included in the initrd, but not mlx4_ib and mlx5_ib. Thus the request_module() call will not find these modules and fail load them. The mlx*_ib module loading will not be retried.
Therefore also include mlx4_ib and mlx5_ib in the initrd to make autoloading them work. A patch is attached to the related Debian bug report.
