46  * SNMP set/get via M_PROTO T_OPTMGMT_REQ.  Structure is that used
47  * for [gs]etsockopt() calls.  get uses T_CURRENT, set uses T_NEOGTIATE
48  * MGMT_flags value.  The following definition of opthdr is taken from
49  * socket.h:
50  *
51  * An option specification consists of an opthdr, followed by the value of
52  * the option.  An options buffer contains one or more options.  The len
53  * field of opthdr specifies the length of the option value in bytes.  This
54  * length must be a multiple of sizeof(long) (use OPTLEN macro).
55  *
56  * struct opthdr {
57  *	long	level;	protocol level affected
58  *	long	name;	option to modify
59  *	long	len;	length of option value
60  * };
61  *
62  * #define OPTLEN(x) ((((x) + sizeof(long) - 1) / sizeof(long)) * sizeof(long))
63  * #define OPTVAL(opt) ((char *)(opt + 1))
64  *
65  * For get requests (T_CURRENT), any MIB2_xxx value can be used (only
66  * "get all" is supported, so all modules get a copy of the request to
67  * return everything it knows.   In general, we use MIB2_IP.  There is
68  * one exception: in general, IP will not report information related to
69  * IRE_MARK_TESTHIDDEN routes (e.g., in the MIB2_IP_ROUTE table).
70  * However, using the special value EXPER_IP_AND_TESTHIDDEN will cause
71  * all information to be reported.  This special value should only be
72  * used by IPMP-aware low-level utilities (e.g. in.mpathd).
73  *
74  * IMPORTANT:  some fields are grouped in a different structure than
75  * suggested by MIB-II, e.g., checksum error counts.  The original MIB-2
76  * field name has been retained.  Field names beginning with "mi" are not
77  * defined in the MIB but contain important & useful information maintained
78  * by the corresponding module.
