Subject: [PATCH v4 net-next 0/2] ionic: add sriov support

Set up the basic support for enabling SR-IOV devices in the
ionic driver.  Since most of the management work happens in
the NIC firmware, the driver becomes mostly a pass-through
for the network stack commands that want to control and
configure the VFs.

v4:	changed "vf too big" checks to use pci_num_vf()
	changed from vf[] array of pointers of individually allocated
	  vf structs to single allocated vfs[] array of vf structs
	added clean up of vfs[] on probe fail
	added setup for vf stats dma

v3:	added check in probe for pre-existing VFs
	split out the alloc and dealloc of vf structs to better deal
	  with pre-existing VFs (left enabled on remove)
	restored the checks for vf too big because of a potential
	  case where VFs are already enabled but driver failed to
	  alloc the vf structs

v2:	use pci_num_vf() and kcalloc()
	remove checks for vf too big
	add locking for the VF operations
	disable VFs in ionic_remove() if they are still running
