I just got bitten by this, so I went looking... the problem is that
setoolkit counts interfaces which have ipackets and opackets in their
definition, but when netif enumerates the interfaces you get many
more. Running net.se:

Name           Ipkts       Ierrs       Opkts       Oerrs       Colls  Coll-Rate
mii                0           0           0           0           0     0.00 %
dmfe_events           0           0           0           0          
0     0.00 %
dmfe0        1014254           0      547487           1           0     0.00 %
mii          1014254           0      547487           1           0     0.00 %
dmfe_events     1014254           0      547487           1          
0     0.00 %
dmfe1              0           0           0           0           0     0.00 %

Changing the kstat definition:

< kstat struct "dmfe:" ks_dmfe_network {
---
> kstat struct "*dmfe" ks_dmfe_network {

but you still get too many:

Name           Ipkts       Ierrs       Opkts       Oerrs       Colls  Coll-Rate
dmfe_events           0           0           0           0          
0     0.00 %
dmfe0        1014389           0      547559           1           0     0.00 %
dmfe_events     1014389           0      547559           1          
0     0.00 %
dmfe1              0           0           0           0           0     0.00 %

There doesn't seem to be anyway to express a kstat structure which
excludes the additional kstat entries. Anyone any ideas, short of
hacking the source?
