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