John?
the lantiq atm/dsl drivers use a dma ring to push packets from the atm
layer to the dsl modem core. this ring needs to be 2 packets big as a
minimum to have the hardware work. however, using software we can make
sure that only 1 packet at a tim eis inside the ring. this is what my
current dirty hack does.
> Btw, I'm looking at ways to *make* BQL on the PPP netdev work
properly, tracking packets all the way to the wire even when it's PPPoA,
PPPoE(oA), L2TP or whatever.
yay :)
