Can two eths run concurent dequeues in 2.4 ?

Hi,

in 2.2 the qdisc dequeues are called from BHs and there are
guaranted that only one BH runs at any time on given
set of CPUs.

In 2.4 timer and dequeues are called AFAIK from softirqs.
Softirqs can run concurently on several CPUs.

So I wonder if dequeue routine of one qdisc can
be called in the same time as dequeue on another
qdisc is running (on another CPU).
And whether timer callback can be called during
dequeue execution (it can't on 2.2).

Thanks, devik
