Linux/TMS320DM8168: EMAC/CPDMA driver will output some abnormal packet (two DM8168 direct connection)

Part Number: TMS320DM8168

Tool/software: Linux

Hi,

We have customized HW with DM8168, recently we found that abnormal packets output while RTP session, (two DM8168 direct connection)

for example, one of abnormal packets contain some information similar to our RTCP packet,

please refer to packet No. 1887 and No. 2927 of attached packet capture, PC 20190307_com_w_rtp_filte.pcap,

because we already confirmed in driver level, there is no such packet was sent from kernel to driver,

it must happen after sending to driver or in CPDMA,

weonder if there were newer version of driver which can be used for DM8168 to fix this,

(our current version was also attached for latest ti-ezsdk_dm816x-evm_5_05_02_00, also attached)
