From 0856f93958c488f0cc656be53c26dfd20663bdb3 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sun, 2 Nov 2008 16:14:27 +0000 Subject: [PATCH] udp: Fix the SNMP counter of UDP_MIB_INERRORS UDP packets received in udpv6_recvmsg() are not only IPv6 UDP packets, but also have IPv4 UDP packets, so when do the counter of UDP_MIB_INERRORS in udpv6_recvmsg(), we should check whether the packet is a IPv6 UDP packet or a IPv4 UDP packet.
