Subject: [PATCH] CHANGES: snmpd: recover SET status from delegated request
Reported by: Yu Zhang of VARAS@IIE, Nanyu Zhong of VARAS@IIE
Fixes by: Arista Networks
When a SET request includes a mix of delegated and
non-delegated requests (e.g., objects handled by master
agent and agentx sub-agent), the status can get lost while
waiting for the reply from the sub-agent. Recover the status
into the session from the requests even if it has already
been processed.

From f5ae6baf0018abda9dedc368fe6d52c0d7a8ab8f Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add Linux 6.7 compatibility parsing /proc/net/snmp
Linux 6.7 adds a new OutTransmits field to Ip in /proc/net/snmp.
This breaks the hard-coded assumptions about the Ip line length.
Add compatibility to parse Linux 6.7 Ip header while keep support
for previous versions.
