I hope your holiday and operation go well Russell. Pardon my ignorance, but I know of quite a few things you have in flight and because of that I'm not entirely sure what specific patches you're referring to above. Have those hit the list? I know you're cleaning up stmmac's phylink/pcs usage, but I'm thinking that this is outside of that series. Thanks in advance for helping me understand all that's in progress around this mess of a topic!
