Zhanfa 폭풍 보호

4.14 커널을 실행하는 ls1021(ARMv7 프로세서 버전 5)에서 gianfar 네트워크 드라이버에 대한 일부 폭풍 방지 매개 변수를 볼 수 있습니다.

/sys/devices/platform/soc/soc:ethernet@2d90000/net/eth0/stormprot_count    
/sys/devices/platform/soc/soc:ethernet@2d90000/net/eth0/stormprot_events    
/sys/devices/platform/soc/soc:ethernet@2d90000/net/eth0/stormprot_current    
/sys/devices/platform/soc/soc:ethernet@2d90000/net/eth0/stormprot_window    
/sys/devices/platform/soc/soc:ethernet@2d90000/net/eth0/stormprot_delay

어떻게 작동하고 어떻게 활성화하나요?

FRAMEREJ_COUNT=60
FRAMEREJ_WINDOW=10
FRAMEREJ_DELAY=500
echo $FRAMEREJ_COUNT > /sys/class/net/eth1/stormprot_count
echo $FRAMEREJ_WINDOW > /sys/class/net/eth1/stormprot_window
echo $FRAMEREJ_DELAY > /sys/class/net/eth1/stormprot_delay

그런 다음 커널은 재부팅하는 대신 네트워크 폭풍이 발생하는 경우 이를 기록합니다.
