[Click] How works Polling??

[Alessandro Baldisserri]

Hi!

I would ask you this... How works polling in Click architecture? (I have e1000
Intel cards). If CPU is scheduling ToDevice element, can PollDevice (and polling
system in general) take the control? Or ToDevice can transfer almost BURST(16)
packets before pass the token at PollDevice? In other words... input of BURST(8)
packets and output of BURST(16) packets are sequential or not? 

Thanks!!
