Maybe the poll is disabling the IRQs on the NIC for too long, or something
like that?
In a reply I just sent out to this thread, I postulate that the
jiffies check is hitting earlier with a lower weight value, a quick
look at /proc/net/softnet_stat during their testing will confirm or
deny this theory.
That would basically just decrease the work done in the NAPI poll though,
so I don't see how that could be the problem, since the 'solution' was to
force less work to be done.
It could also just be a simple bug in the dev->quota accounting
somewhere.
Note that, in all of this, I do not have any objections to providing
a way to configure the dev->weight values. I will be applying Stephen
Hemminger's patches.
Good. The more knobs the merrier, so long as they are at least somewhat
documented and default to good sane values :)
