From: Hanumanth Pothula <[email protected]> Some of the HW has support for choosing memory pools based on the packet's size. The pool sort capability allows PMD/NIC to choose a memory pool based on the packet's length.
On multiple mempool support enabled, populate mempool array and also print pool name on which packet is received.
