It looks like you are saying that there is a bug that makes TX stop when you run the following commands: testpmd> start testpmd> show port info 0 I don't see such bug, could you explain better the steps to reproduce the issue?

I observed this on Intel 82577LM(em). Basically show port info will read PHY registers to get link status when lsc interrupt was disabled, which caused TX to stop. I don't have other NICs so not sure it is a common issue or not.
