staging: lustre: lnet: add per NI configuration structures
Currently for LNet all hardware configuration is done with the modprobe configuration file. These settings are applied to all hardware instances for a node. That makes it impossible to configure two different pieces of infiniband hardware that require very different settings to function. Here we introduce the infrastructre to allow applying per interface settings.
