Subject: [PATCH] net/mlx4_core: Warn if device doesn't have enough PCI
 bandwidth

Check if the device get enough bandwidth from the entire PCI chain to satisfy
its capabilities. This patch determines the PCIe device's bandwidth capabilities
by reading its PCIe Link Capabilities registers and then call the
pcie_get_minimum_link function to ensure that the adapter is hooked into a slot
which is capable of providing the necessary bandwidth capabilities.
