Re: Are there any alternatives to IFB for downlink shaping?

Hi Marco,

"action skbedit" is a simple tc action that edits skb packets in fairly straightforward ways, e.g. "action skbedit mark 1" edits the filtered packet to have mark = 1.

Generally, I prefer "tc filter" commands to "iptables -A" commands, mainly because the former are bound to an individual interface rather than to every netfilter chain call ever. :-)

> I now have tc doing this beautifully on the uplink traffic (I use 'action skbedit mark 1', why is this trick mentioned hardly anywhere?): but, like almost every other first time poster here :-) , I'm having no luck at all getting this working for downlink traffic.

?! Looking on google form 'skbedit' lead me to multiqueue management:

and seems not related... can you explain better?
