From: Helge Deller <[email protected]> Translate host error codes of IP_RECVERR and IPV6_RECVERR control messages to target error codes before returning to the caller. For example, this is important for architectures (e.g. hppa, alpha, sparc, mips) on which the value of ECONNREFUSED is different to the value on a x86_64 host.
