I understand that some drivers support jumbo frame and if it receive jumbo packet (greater than 1500 byte), it creates mbuf chains and pass it to DPDK application through e.g. rte_eth_rx_burst. However it looks that ixgbe driver does not support jumbo frame. Q1. Is my understanding above correct? Q2. If A1 equals YES, then are there any future plan to support jumbo frame on ixgbe?
