v5.0.1 switch reports WARNING when connected/synchronized to v6.0 switch
I had v5.0.1 "switch B" connected to v6.0 "switch A" in the lab. The v5.0.1 "switch B" was reporting WARNING and I was convinced its for another reason... but now I've downgraded "switch A" to v5.0.1 and all is green.... needs to be investigated before release
