commitedf391ff17("snmp: add missing counters for RFC 4293") had already added OutOctets for RFC 4293. In commit2d8dbb04c6("snmp: fix OutOctets counter to include forwarded datagrams"), OutOctets was counted again, but not removed from ip_output(). According to RFC 4293 "3.2.3. IP Statistics Tables", ipipIfStatsOutTransmits is not equal to ipIfStatsOutForwDatagrams. So "IPSTATS_MIB_OUTOCTETS must be incremented when incrementing" is not accurate. And IPSTATS_MIB_OUTOCTETS should be counted after fragment. This patch reverts commit2d8dbb04c6("snmp: fix OutOctets counter to include forwarded datagrams") and move IPSTATS_MIB_OUTOCTETS to ip_finish_output2 for ipv4.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
