whenever use the P2020 CPU core 1 to handle etsec interrupt ,there is packet loss

Hi all,

I use p2020rdb-pc to design a firewall product.

ETH2 and ETH1 is configured to a bridge,to do packet forward. I set the smp_affinity to use the CPU core0 for both the eth2 and eth1,I can get a throuput test result,about 7%(gigabit) at 64-byte packet.

whenever I set the smp_affinifty to CPU core1, there is packet loss,even at %1 load.

I am looking forward to get your help!

Thanks

Yinzhi

It's resolved . It is a thing caused by wrong DTB file
