We, USAGI, have similar code for linux-2.4. (Sorry, I forgot this 
one... :-p)

We store per-interface in inet6_dev{}, because this information blongs 
to inet6 layer.

I'd recommend that we split information per interface
 1) to minimize the /proc file
 2) to minimize the effort to rewrite snmp daemon (e.g. net-snmp)
We use /proc/net/dev_snmp6/{1,2,...}. Example:

# cat /proc/net/dev_snmp6/1
Ip6LastChange                           1616
Ip6InReceives                           1108
Ip6InHdrErrors                          0
Ip6InTooBigErrors                       0
:
Icmp6InMsgs                             1107
Icmp6InErrors                           549
Icmp6InDestUnreachs                     1106
