xymon 4.2.2/Solaris 10/ifstat "mac" interface

Hi,

The kstat command issued by xymon is generating a network statistic  

called "mac" which gives exactly the same stat than the driver/ instanciated one (bge0 in my case).

This is annoying for two reasons :
	- this lead to confusion
	- too many "RRD error updating blabla/ifstat.mac.rrd from blabla :  

illegal attempt to update using time 123 when last update time is 123
(minimum one second step)

I'd appreciate any help
