Make it possible to use ix(4) with MSI-X, currently disabled by default.
The current implementation still uses a single queue but already establishes
a different handler for link interrupts. This is done in preparation for
multi-queues support.
Based on a bigger diff from haesbaert@ and on the FreeBSD code.
Tested by Hrvoje Popovski and jmatthew@, ok jmatthew@
