看 top 页面的时候看到了这进程,谷歌搜了下好像是普遍状况。在 miui.eu 论坛找到了解决办法。是 /vendor/etc/init/init.qcom.rc 启动的。内容如下
``` service vendor.tcpdump /vendor/bin/tcpdump -i any -W 2 -C 2 -s 134 -w /data/vendor/wlan_logs/tcpdump.pcap class main user root group root wifi disabled oneshot
service sniffer /vendor/bin/tcpdump -i wlan0 -w /sdcard/wlan_logs/sniffer.pcap class main user root group root disabled oneshot ```
