In particular the xpcs_soft_reset() and xpcs_do_config() functions currently return -1 if invalid auto-negotiation mode is specified. That value can be then passed to the generic kernel subsystems which require a standard kernel errno value. Even though the error conditions are very specific (memory corruption or buggy implementation) using a hard-coded -1 literal doesn't seem correct anyway.
