Update sfc_netback driver to match sfc_resource 3.0.2.2074
Add support for direct guest access and acceleration of SFC9000 series
NICs.
Improve handling of NIC reset in sfc_netback
Remove nic_index state and replace with if_index from struct
net_device Remove duplication of header files with sfc_resource driver
