>
> From: Ady Agbarih <adypodo...@gmail.com>
>
> The number of QPs for a device are setup during the
> configuration phase, when the user calls
> rte_regexdev_configure(). The mlx5 regex driver then
> pre-allocates QPs, however those QPs are not
> setup/ready for sending jobs. The user has to configure
> each QP using rte_regexdev_queue_pair_setup(). When
> stopping the device the driver destroys all QPs that
> were preallocated assuming that they are all setup. This
> results in an attempt to destroy an uninitialized QP,
> leading to a NULL dereference error.
>
> In order to solve this issue we first check that the
> QP jobs array has been initialized before attempting
> to destroy the QP.
