enable to remove SNMP timer (which consumne several cycles even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only when it's queried (any direct call to "sysuptime" is changed by a call to snmp_get_sysuptime).

* snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
when it's queried (any direct call to "sysuptime" is changed by a call to
snmp_get_sysuptime).

* igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
