iwn - Intel Centrino Ultimate-N 6300 - systat missing counters

[Andrei Brezan]

Hello list,

I have a Lenovo T510 with a Intel Centrino Ultimate-N 6300 wireless 
adapter. I recently noticed that while using "systat 1 -if" the output 
traffic shows as 0 always while on netstat -i I can see Opkts increasing 
for the wlan interface. Anyone knows where this issue can arise?

The card if using the iwn driver:

iwn0: <Intel Centrino Ultimate-N 6300> mem 0xf2000000-0xf2001fff irq 17 
at device 0.0 on pci3

on 10.0-RELEASE-p4

Thank you,
