4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Kashyap Desai <[email protected]> commit 18e1c7f68a5814442abad849abe6eacbf02ffd7c upstream. For SRIOV enabled firmware, if there is a OCR(online controller reset) possibility driver set the convert flag to 1, which is not happening if there are outstanding commands even after 180 seconds. As driver does not set convert flag to 1 and still making the OCR to run, VF(Virtual function) driver is directly writing on to the register instead of waiting for 30 seconds. Setting convert flag to 1 will cause VF driver will wait for 30 secs before going for reset.
