Currently the buffer used for control VQ commands is protected by the RTNL lock. Previously this wasn't a major concern because the control VQ was only used during device setup and user interaction. With the recent addition of dynamic interrupt moderation the control VQ may be used frequently during normal operation. This series removes the RNTL lock dependancy by introducing a spin lock to protect the control buffer and writing SGs to the control VQ.
