Hi, I'm trying to send and receive jumbo frame ethernet packets. While sending works without any issues, I always receive fragmented / segmented packets. This leads me to the following questions: 1. Is it possible to receive a frame without segmentation 2. How to properly size the mempool elements. Here, I tried the following (pkt_bytes is the maximum expected frame size): buf_size = RTE_PKTMBUF_HEADROOM + pkt_bytes; rte_mempool_create(mempool_name, NB_MBUF, buf_size, MAX_PKT_BURST, sizeof(struct rte_pktmbuf_pool_private), rte_pktmbuf_pool_init, NULL, rte_pktmbuf_init, NULL, rte_socket_id(), MEMPOOL_F_SP_PUT | MEMPOOL_F_SC_GET); Some experiments with various buf_sizes showed, that if I make the buffer large enough (e.g. pkt_bytes * 2) it seems to work at least for some NICs (with IXGBE driver).
