Tool/software:
hello：
We use P2P pressure test for about 12 hours, unable to ping am62;Eth0 cannot be pinged, but vlan can be pinged.After capturing tcpdump, it can ping eth0 and am62 normally.
After a period of P2P pressure testing, there may be a situation where ping is not possible. Only by enabling eth0's mixed mode can normal ping be achieved
and the am62 sdk version is tidl_am62a_08_06_00_10
