From: Stefan Assmann <sassm...@kpanic.de>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
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.
