Hi. I look into SFQ(Stochastic Fair Queueing) In ALTQ.
And.. I Have 1 questions...
When packet dropping,
first check q length(HWM) and search logest q.
It means... ALTQ use Common Buffer Pool shared multiple queues(SFQ
defaults queue number 255. right?)
Why implements Common Buffer Pool?
I mean... when q length leaches HWM, why search? Just dropping
Is it any advantage in using common buffer pool?(I mean..
implementation complexity.. or existing kernel backward compatibility
or... ... ??? )

Thx in advance.
