[Click] click v.s. NAPI

[zliu at bohuatech.com]

Hi, Eddie:

>From pure performance point of view, could you comment on
the pros and cons between click pure polling and NAPI's
mixed interrupt and polling for gigabit router/firewalls.

Also, since click bypass linux stack, can I still use it with
things like iptables, or I must use one of the click counterparts.
