Detected '1' late Ethernet frames

[zinkg]

I am running srsRAN with an RU using the ORAN 7.2 split configuration and seeing consistent late Ethernet frames messages in the gnb.log file. Sample from gnb.log below.

Has anyone seen this warning before? What causes this warning?

hi @zinkg any update on this issue?

Hello, did you find something in code on how timing synchronization is happening and why these late packets are coming or some packets/slots are getting missed
