网卡处理每一个 packet 都要占用中断，而百兆网卡，1400 字节以上大包跑满才不过几千
但如果让 64 字节的小包跑到 50M，pps 也要远比上面说的大的多，负载也要大的多

我坚持我的看法，网卡的负载要看 pps，而 ...

CONFIG_E1000_NAP
    NAPI is a new driver API designed to reduce CPU and interrupt load
when the driver is receiving lots of packets from the card. It is
still somewhat experimental and thus not yet enabled by default.
    If your estimated Rx load is 10kpps or more, or if the card will be
deployed on potentially unfriendly networks (e.g. in a firewall),
then say Y here.
    See Documentation/networking/NAPI_HOWTO.txt for more
information.
    If in doubt, say N.                    

不知道该怎么办了。。。
