The MFW manages an internal lock to prevent concurrent hardware (de)initialization of different PFs. This, together with the busy-waiting for the MFW's responses for commands, might lead to a deadlock during concurrent load or unload of PFs. This patch adds the option to sleep within the busy-waiting, and uses it for the (un)load requests (which are not sent from an interrupt context) to prevent the possible deadlock.
