snmp: fix OutOctets counter to include forwarded datagrams
RFC 4293 defines ipIfStatsOutOctets (similar definition for
ipSystemStatsOutOctets):
The total number of octets in IP datagrams delivered to the lower
layers for transmission. Octets from datagrams counted in
ipIfStatsOutTransmits MUST be counted here.
And ipIfStatsOutTransmits:
The total number of IP datagrams that this entity supplied to the
lower layers for transmission. This includes datagrams generated
locally and those forwarded by this entity.
Therefore, IPSTATS_MIB_OUTOCTETS must be incremented when incrementing
IPSTATS_MIB_OUTFORWDATAGRAMS.
IP_UPD_PO_STATS is not used since ipIfStatsOutRequests must not
include forwarded datagrams:
The total number of IP datagrams that local IP user-protocols
(including ICMP) supplied to IP in requests for transmission. Note
that this counter does not include any datagrams counted in
ipIfStatsOutForwDatagrams.
