d0c3baf340 Partly apply Elias Oenal's SNMP V3 patch. There is more to come, the work is incomplete at the moment and does not compile when LWIP_SNMP_V3 is enabled. 2016-03-29 10:28:33 +02:00

7b946fa9b1 SNMP agent rewrite
- SNMPv2c support
  - Greatly reduced RAM usage, no memory pools any more
  - API cleanup
  - MIB2 is separated from SNMP stack
  - Support for multiple MIBs (snmp_set_mibs call) - e.g. for private MIB
  - Improved MIB2 implementation (tcpConnTable etc.)
  - Redesigned simple and generic API for MIB implementation
  - Comfortable node types for scalar arrays and tables
  - Counter64, bit and truthvalue datatype support
  - Callbacks for SNMP writes
  - Runs on two APIs: RAW and netconn
  - Async API is gone - the stack now supports netconn API instead,
    so blocking operations can be done in MIB calls.
    SNMP runs in a worker thread when netconn API is used.
  - Simplified thread sync support for MIBs - useful when MIBs
    need to access variables shared with other threads without locking
    (used in MIB2 to access lwIP stats from lwIP thread)

Currently in work:
  - Traps rewrite
  - MIB compiler
