Or can those be > simply ignored? If so then I will ask UDP app vendors to use IP_RECVERR. If you don't set MSG_ERRQUEUE, no special error reports will be given to the application. And this only matters for recvmsg() handling. On send, the only behavior difference is this error code reporting (and before Eric's patch, SNMP statistics handling). -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
