T-engines show RX packet loss of ~5% #9

Closed jaycedowell closed 1 year ago

The T-engines do not seem to be receiving packets from the DRX pipelines.

Update from 2023/9/1: Seems to be working with two beams + fixes to the ibeam# header + new sending structure in ndp_drx.py. For the header all uint8_t fields are now uint16_t. Packet capture looks reasonable but there some packet loss (~5%).

Updated the title to reflect the new problem.

The packet loss is still ~5% after doubling the gulp size of 3820 spectra and only running CaptureOp. Maybe this is something with the timing of packets coming from the two servers?

Turning flow control on for the server ports on the switch drops the packet loss to 0%.
