52  * SNMP set/get via M_PROTO T_OPTMGMT_REQ.  Structure is that used
53  * for [gs]etsockopt() calls.  get uses T_CURRENT, set uses T_NEOGTIATE
54  * MGMT_flags value.  The following definition of opthdr is taken from
55  * socket.h:
56  *
57  * An option specification consists of an opthdr, followed by the value of
58  * the option.  An options buffer contains one or more options.  The len
59  * field of opthdr specifies the length of the option value in bytes.  This
60  * length must be a multiple of sizeof(long) (use OPTLEN macro).
61  *
62  * struct opthdr {
63  *	long	level;	protocol level affected
64  *	long	name;	option to modify
65  *	long	len;	length of option value
66  * };
67  *
68  * #define OPTLEN(x) ((((x) + sizeof(long) - 1) / sizeof(long)) * sizeof(long))
69  * #define OPTVAL(opt) ((char *)(opt + 1))
70  *
71  * For get requests (T_CURRENT), any MIB2_xxx value can be used (only
72  * "get all" is supported, so all modules get a copy of the request to
73  * return everything it knows.   In general, we use MIB2_IP.  There is
74  * one exception: in general, IP will not report information related to
75  * ire_testhidden and IRE_IF_CLONE routes (e.g., in the MIB2_IP_ROUTE
76  * table). However, using the special value EXPER_IP_AND_ALL_IRES will cause
77  * all information to be reported.  This special value should only be
78  * used by IPMP-aware low-level utilities (e.g. in.mpathd).
79  *
80  * IMPORTANT:  some fields are grouped in a different structure than
81  * suggested by MIB-II, e.g., checksum error counts.  The original MIB-2
82  * field name has been retained.  Field names beginning with "mi" are not
83  * defined in the MIB but contain important & useful information maintained
84  * by the corresponding module.
