When the next user come along, we can reconsider. Ok. Thanks for clarification. I performed some additional tests to make sure the bug was on the PHY side. They proved my original conclusion. It's indeed Realtek PHY to blame for the weird behavior. So I've added a few more words into the patch log regarding those tests. The patch will be resent tomorrow together with the rest of the STMMAC-driver-related bug-fixes detached from the original series of the fixes and cleanups (as Andrew asked to do). -Sergey > > Andrew
