I dont know of any ordering dependencies with pppoe. Is this a bug
in the ppp code?

Yes it is ;->
The effects of your patch could be achieved in two ways:
a) tie the pppoe related ethernet card to a processor.
b) use a NAPI caopable ethernet card.
Now, if there is a real need to have a serialization queue (i dont see
one) you really dont need to tie to a processor. Just have a single queue
shared by all processors; every one grabs a lock to it.
