> We made some effort to reduce the RTNL lock scope when resetting and
> rebuilding the PF. Unfortunately we still held the RTNL lock during the VF
> reset operation, which meant that multiple PFs could not reset in parallel due
> to the global lock. For now, further reduce the scope by not holding the RTNL
> lock while resetting VFs. This allows multiple PFs to reset in a timely manner.
