[Xen-devel] proposal of xt_physdev's patch to limit traffic

[ahmed amamou <ahmed.amamou@xxxxxxxxxxx>]

Good morning every Body

I'm new in modules programming and I've made a patch to limit packet traffic in bridge(patch is joined with the mail).

In order to limit the traffic, i used the netback limitation method to count traffic with skb->len  for each vif to stop traffic, as i can't put down vif, i change the hotdrop flag to 1 (change was based on xt_physdev of dom 0 2.6.18.8 so  in the patch will find it 1 but it's easy to change the patch to recent dom 0 version by just changing  *hotdrop=1; to *par->hotdrop=true;)

The problem that i have is that when i reach traffic limit (30mb/s by defaut and can be changed via proc EX: "echo vif1.0 312500,50000' >/proc/changeRXrate know that doing it via proc is the worst way but i don't know any other way to do it any suggestion will be welcome ) and begin drop traffic fell terribly and became 10mb/s

will be really thankful if anybody could help me with suggestions and advices in order to  solve this problem


Sincerly
