i'm not sure if they refer to the media access control or the medium access controller. my guess its the latter as net would probably define the hardware its running on. i'm wondering if someone who has a ring network will show a class of ring.

kstat_data_lookup
kstat_lookup(3KSTAT) Kernel Statistics Library Functions kstat_lookup(3KSTAT)
NAME
kstat_lookup, kstat_data_lookup - find a kstat by name
SYNOPSIS
cc [ flag... ] file... -lkstat [ library...]
#include <kstat.h>
kstat_t *kstat_lookup(kstat_ctl_t *kc, char *ks_module, int ks_instance,
char *ks_name);
void *kstat_data_lookup(kstat_t *ksp, char *name);
DESCRIPTION
The kstat_lookup() function traverses the kstat chain, kc->kc_chain, searching for a kstat with the same ks_module, ks_instance, and
ks_name fields; this triplet uniquely identifies a kstat. If ks_module is NULL, ks_instance is -1, or ks_name is NULL, those fields will
be ignored in the search. For example, kstat_lookup(kc, NULL, -1, "foo") will find the first kstat with name "foo".
The kstat_data_lookup() function searches the kstat's data section for the record with the specified name. This operation is valid only for
those kstat types that have named data records: KSTAT_TYPE_NAMED and KSTAT_TYPE_TIMER.
RETURN VALUES
The kstat_lookup() function returns a pointer to the requested kstat if it is found. Otherwise it returns NULL and sets errno to indicate
the error.
The kstat_data_lookup() function returns a pointer to the requested data record if it is found. Otherwise it returns NULL and sets errno to
indicate the error .
ERRORS
The kstat_lookup() and kstat_data_lookup() functions will fail if:
EINVAL An attempt was made to look up data for a kstat that was not of type KSTAT_TYPE_NAMED or KSTAT_TYPE_TIMER.
ENOENT The requested kstat could not be found.
