> 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.
