> 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.
