Traditionally Intel based NIC drivers request I/O port even though it
doesn't need that really.
Intel PCIE 10Gb driver (ixgbe) also requests I/O port but it doesn't
need it either.
This is a little inconvenient situation because sometimes we have to
handle those cards on the slots where any I/O space is not attached.
So we made pach which makes ixgbe driver legacy I/O port free.
