Change code from PRC_UNREACH_ADMIN_PROHIB to PRC_UNREACH_PORT for ICMP_UNREACH_PROTOCOL and ICMP_UNREACH_PORT And let TCP treat PRC_UNREACH_PORT like PRC_UNREACH_ADMIN_PROHIB This should fix the case where port unreachables for udp returned ENETRESET instead of ECONNREFUSED Problem found by: Bill Fenner <fenner@research.att.com> Reviewed by: jlemon
