Having those available simultaneously would let me do some very neat th= ings in sch_cake, and potentially other future work too. I have a working 4.1rc3 version now but it is either without or with the 5 tuple hash. Still haven't decoded how to use the api. I would like to also have something that could use a dest mac hash instead, this would (with an increased quantum) make it possible to look harder at per-station queuing (at this layer) for wifi. (still, think we need to be working at the mac80211 layer for that, but...) > > - Jonathan Morton > --=20 Dave T=C3=A4ht Open Networking needs **Open Source Hardware** https://plus.google.com/u/0/+EricRaymond/posts/JqxCe2pFr67
