6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Harshitha Ramamurthy <hramamurthy@xxxxxxxxxx>
commit de70981f295e7eab86325db3bf349fa676f16c42 upstream.
When a queue is stopped using the ndo queue API, before
destroying its page pool, the associated NAPI instance
needs to be unlinked to avoid warnings.
Handle this by calling page_pool_disable_direct_recycling()
when stopping a queue.
Cc: stable@xxxxxxxxxxxxxxx
Fixes: ebdfae0d377b ("gve: adopt page pool for DQ RDA mode")
