Hello:

This series was applied to netdev/net-next.git (main)
by Paolo Abeni [off-list ref]:

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 dependency by introducing a mutex
to protect the control buffer and writing SGs to the control VQ.
