可能找到问题的正确解决办法了
在内核中发现这样一个参数
[ *] Intel(R) PRO/1000 Gigabit Ethernet support
[ ] Use Rx Polling (NAPI)
其具体描述如下
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.
