linuxptp issues on ls1021atsn

i want to run linuxptp on ls1021astn,but faced some issues.

first, ls1021ATSN runs openIL(2020.02,linux kernel5.4).

then ls1021atsn act as a P2P-TC switch(typing cmd like this: ptp4l -i swp2 -i swp3 -i swp4 -f P2P-TC.cfg -m )，connected to a pc1(master clock),to pc2 and pc3( 2 slave clocks).

finally, two slave clock print multiple peer responses and rogue peer delay.

if just one slave clock,P2P-TC works well.
