Description

While moving LNet to netlink in my testing of different lnetctl command options bugs were exposed. Some of the bugs are:

1) A double free in the kernel when settting up a LNet NI for an interface that doesn' exis.t

2) NI tunables not being properly set.

3) A memory leak when registering a LNet NI twice.

4) Better range handling of user input and less strict failing for bad parameters.
