ad7775dc7b ibmvnic: map L2/L3/L4 header descriptors to firmware 
Allow the VNIC driver to provide descriptors containing
L2/L3/L4 headers to firmware.  This feature is needed
for greater hardware compatibility and enablement of checksum
and TCP offloading features.

A new function is included for the hypervisor call,
H_SEND_SUBCRQ_INDIRECT, allowing a DMA-mapped array of SCRQ
descriptor elements to be sent to the VNIC server.

These additions will help fully enable checksum offloading as
well as other features as they are included later.

de89e854bc ibmvnic: Fix ibmvnic_capability struct 
The ibmvnic_capability struct was defined incorrectly. The last two
elements of the struct are in the wrong order.  In addition, the number
element should be 64-bit. Byteswapping functions are updated
as well.

032c5e8284 Driver for IBM System i/p VNIC protocol 
This is a new device driver for a high performance SR-IOV assisted virtual
network for IBM System p and IBM System i systems.  The SR-IOV VF will be
attached to the VIOS partition and mapped to the Linux client via the
hypervisor's VNIC protocol that this driver implements.

This driver is able to perform basic tx and rx, new features
and improvements will be added as they are being developed and tested.
