Hi, Does DPDK support to free the transmitted buffers to external cache which is provided during tx queue configurations (rte_eth_tx_queue_setup). This is needed to extract better performance when multiple tx queues are being worked on by unregistered non-eal pthreads which sends the packets (mbuf from common rte_mempool) to the queue parallelly using rte_eth_tx_burst. Otherwise, they are bypassed frim local cache and go to the path of CAS operation on the common pool for free operation. Or is there any other way to achieve this? Thanks Syed
