39a0dd0b5e net: thunderx: remove unneeded type conversions 
No need to cast void* to u8*: pointer arithmetics

fd7ec06254 net: thunderx: add static 
This fixes sparse messages like this:

drivers/net/ethernet/cavium/thunder/nicvf_main.c:1141:26: sparse: symbol
'nicvf_get_stats64' was not declared. Should it be static?

Also remove unused declarations

4863dea3fa net: Adding support for Cavium ThunderX network controller 
This patch adds support for the Cavium ThunderX network controller.
The driver is on the pci bus and thus requires the Thunder PCIe host
controller driver to be enabled.
