I ecountered many problems with mvm in this tree, Eyal quickly fixed the rs unending search cycle, you told me the monitor deadlock was already filed internally on your side, the ones I mentioned in this thread, also it seems that with the 7260-8.ucode I don't get anything on a monitor iface except the mere traffic of another associated iface (when I have such one). Except maybe for the latter?, these bugs seem easy enough to trigger and alarming enough that I suspect you already must be on your way to fixing what you deem needs to .. and thus I did not feel bad not dissecting or reporting further and droping this tree with iwlwifi. I hope this clarifies the meaning and intention of the last sentence. I have been using the 7260 since last summer and, as I already mentioned to Johannes, found it very useful, and wouldn't mind giving some other out-of-tree patches a go.
