Subject: [IPv6] SNMP: Restore Udp6InErrors incrementation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7a0ff716c2282f4b8d89c65850a4f17399628154;p=openwrt%2Fstaging%2Fblogic.git

[IPv6] SNMP: Restore Udp6InErrors incrementation

As the checksum verification is postponed till user calls recv or poll,
the inrementation of Udp6InErrors counter should be also postponed.
Currently, it is postponed in non-blocking operation case. However it
should be postponed in all case like the IPv4 code.
