The 'eth_check_reta_mask()' & 'eth_check_reta_entry()' static fucntions are also
checking 'reta_conf' against NULL, they may be removed after these checks.

This is internal API, not sure if needed to verify 'dev' here, it won't hurt of
course, but just to prevent unnecessary checks. No strong option.
Same comment for all internal functions that changed.

Function documentation in the header file, doesn't list '-EINVAL' as a return
value, whenever a new return value is returned, it needs to be documented.
