I guess ppp dropping GSO, but is it should be there on first place?
GSO is disabled on all ethernet interfaces.

And as i see GRO enabled there, i guess it can be harmful for shapers,
how to disable it?
NewNet-PPPoE ~ # ethtool -K ppp0 gro off
Cannot set device GRO settings: Operation not supported
Or there is no need for that?

No need, since GRO sits on top of NAPI (physical devices)
ppp is done after this layer, frames are directly delivered to IP layer.
But yes, this log flood is nasty.

Linus released 2.6.39 before I could merge the patch that gets rid
of this, will send it to 2.6.39-stable.
