udp: Fix the SNMP counter of UDP_MIB_INDATAGRAMS
If UDP echo is sent to xinetd/echo-dgram, the UDP reply will be received
at the sender. But the SNMP counter of UDP_MIB_INDATAGRAMS will be not
increased, UDP6_MIB_INDATAGRAMS will be increased instead.
Endpoint A Endpoint B
UDP Echo request ----------->
(IPv4, Dst port=7)
<---------- UDP Echo Reply
(IPv4, Src port=7)
This bug is come from this patch cb75994ec311b2cd50e5205efdcc0696abd6675d.
It do counter UDP[6]_MIB_INDATAGRAMS until udp[v6]_recvmsg. Because
xinetd used IPv6 socket to receive UDP messages, thus, when received
UDP packet, the UDP6_MIB_INDATAGRAMS will be increased in function
udpv6_recvmsg() even if the packet is a IPv4 UDP packet.
This patch fixed the problem.
