   *5.9.1*:
     General: Many bug fixes
   *5.9*
     snmplib:
      - Add IPv6 support to DTLSUDP transport
      - use new netsnmp_sockaddr_storage in netsnmp_addr_pair
      - add base_transport ptr for tunneled transports
      - Add support for OpenSSL 1.1.1
      - Dtls: overhaul of debug
      - Remove inline versions of container funcs
     snmpd:
      - Use ETHTOOL_GLINKSETTINGS when available Newer Linux kernels
	support ETHTOOL_GLINKSETTINGS. Use it when available instead of the
	older and deprecated ETHTOOL_GSET. This patch avoids that the Linux
	kernel reports the following kernel warning: warning: 'snmpd' uses
	legacy ethtool link settings API, link modes are only partially
	reported See also https://sourceforge.net/p/net-snmp/patches/1387/.
	[bvanassche: reworked this patch significantly]
      - Reduce the time needed to execute "pass" scripts on BSD systems See
	also https://github.com/net-snmp/net-snmp/issues/8.
      - [BUG 2926]: Make it possible to set agentXPingInterval for a
	subagent - register agentXPingInterval for the subagent list
	handler, before it was registered for snmp - added agentxTimeout to
	the subagent list handler. It's now possible to set for snmpd and
	the subagent. See 'man snmpd.conf' - added agentxRetries to the
	subagent list handler. See 'man snmpd.conf'. It's never used in the
	subagent, but it's now following the documentation Signed-off-by:

     snmptrap:
      - BUG: 2899: Patch from Drew Roedersheimer to set library
	engineboots/time values before sending
     snmptrapd:
      - Add support for the latest libmysqlclient version
     libsnmp:
      - Scan MIB directories in alphabetical order This guarantees that
	e.g. mibs/RFC1213-MIB.txt is read before mibs/SNMPv2-MIB.txt. The
	order in which these MIBs is read matters because both define
	sysLocation but with different attributes.
     unspecified:
      - [BUG 2930]: Fix a Solaris hrSWInst crash Avoid that snmpd crashes
	on Solaris when querying software packages with an empty CATEGORY
	field. See also https://sourceforge.net/p/net-snmp/bugs/2930/. See
	also https://sourceforge.net/p/net-snmp/patches/1390/.
     FreeBSD:
      - Fix first byte of IF-MIB::ifPhysAddress   Don't write past the
	interface name, and use temporary copy instead. This fixes the
	first byte of ifPhysAddress always being 0 on FreeBSD. See also
	https://sourceforge.net/p/net-snmp/code/merge-requests/20/. [
	bvanassche: edited patch title / added test for malloc() result /
	reduced number of free(if_name) calls ]
     Win32:
      - BUG: 2779541 Fixed handle leak in pass_persist.
