How to enable flow control of eqos driver for 1GbE J14(3&4)

Dear @Tabito.Suzuki,
Could you check with DRIVE OS 5.2.6 release? Also, could you check the stats with iperf?

@SivaRamaKrishnaNV

I haven’t found any perfomance improvement at J14(3&4) in DRIVE OS 5.2.6 release notes(NVIDIA DRIVE Documentation | NVIDIA Developer).
Do you mean this issue has been fixed in 5.2.6? Did you check the stats with iperf?

We can’t update os version easily.

Dear @Tabito.Suzuki,
We have verified on DRIVE OS 5.2.6 and notice 20% packet drop at Tegra A and 2% drop at Tegra B We sent packets 256Mbps from XavierA/Xavier B to Host

Dear @SivaRamaKrishnaNV ,
You meant that packet drop is happened necessarily at Tegra A and B ?
We notice no packet drop from our PC’sCoreA/Core B to Host.
Why is packet drop occurs? Is there any method reduces packet drop same as PC ?
