The infiniband section must be defined for the OS
to use the IB link. If it is missing then networking
does not come up during firstboot.
Fix this by having an inifiniband section including explicitly
declaring use of datagram mode. This should suffice for all
install use cases, and may be changed after firstboot starts.
If the ip command shows altnames, do not
let the altnames interfere with locking
on to linktype.
Further, use show dev instead of grep to be more specific.
When booting and infiniband comes up as the 'get started' nic,
make the entry use correct type so as to avoid
confusion later, particularly when confignet comes along to fixup
the configuration.
