3.13.11.6 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Stefan Assmann <[email protected]> commit 76252723e88681628a3dbb9c09c963e095476f73 upstream. To properly re-initialize SR-IOV it is necessary to reset the device even if it is already down. Not doing this may result in Tx unit hangs.
