> Subject: [PATCH] net/iavf:fix slow memory allocation
> 
> In some cases, the DPDK does not allocate hugepage heap memory to some
> sockets due to the user setting parameters (e.g. -l 40-79, SOCKET 0 has no
> memory).
> When the interrupt thread runs on the corresponding core of this socket,
> each allocation/release will execute a whole set of heap allocation/release
> operations,resulting in poor performance.
> Instead we call malloc() to get memory from the system's heap space to fix
> this problem.
> 
> Fixes: cb5c1b91f76f ("net/iavf: add thread for event callbacks")
