> Subject: [PATCH v7] net/ice: fix ice dcf control thread crash
>
> The control thread accesses the hardware resources after the resources were
> released, which results in a segment error.
>
> The 'ice-reset' threads are detached, so thread resources cannot be
> reclaimed by `pthread_join` calls.
>
> This commit synchronizes the number of "ice-reset" threads by adding a
> variable ("vsi_update_thread_num") to the "struct ice_dcf_hw" and
> performing an atomic operation on this variable. When releasing HW
> resources, we wait for the number of "ice-reset" threads to be reduced to 0
> before releasing the resources.
