Ethernet not consistent

[Sagar281]

Ethernet communication seems to be inconsistent,some packets getting dropped when iperf is performed.

Root Cause: To be Identified

Next Step/Observations:

Need to Identify if the issue is between RJ45 connector and ethernet switch OR between Ethernet switch and LTE-SoC.
To check the integrity between RJ45 and ethernet switch, ethernet conpliance test/eye diagram analysis to be performed.
If above possibility is ruled out, then the issue is between ethernet switch and LTE-SoC. To dubug further, all SGMII/SERDES register values to be verified.
