TSO and packets accounting

[Slawa Olhovchenkov]

How to acoount output packets w/ TSO?
I mean as one large packet. What I see:

# netstat -nbI lagg0 1
            input          lagg0           output
   packets  errs idrops      bytes    packets  errs      bytes colls
   1702715     0     0  122228560    6274492     0 9401968581     0
   1623416     0     0  116306353    6035291     0 9045680036     0

9401968581/6274492 = 1498.44299442887169192342

TSO not worked?
Or this is adapted acounting?
