So, CRC will be stripped even when the\n+``rxmode.hw_strip_crc`` member is set to 0 in ``struct rte_eth_conf``.\n+\n+Maximum packet length\n+~~~~~~~~~~~~~~~~~~~~~\n+\n+The ThunderX SoC family NICs support a maximum of a 9K jumbo frame. The value\n+is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len``\n+member of ``struct rte_eth_conf`` is set to a value lower than 9200, frames\n+up to 9200 bytes can still reach the host interface.\n+\n+Maximum packet segments\n+~~~~~~~~~~~~~~~~~~~~~~~\n+\n+The ThunderX SoC family NICs support up to 12 segments per packet when working\n+in scatter/gather mode. So, setting MTU will result with ``EINVAL`` when the\n+frame size does not fit in the maximum number of segments.\n+\n+Limited VFs\n+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+The ThunderX SoC family NICs has 128VFs and each VF has 8/8 queues\n+for RX/TX respectively. Current driver implementation has one to one mapping\n+between physical port and VF hence only limited VFs can be used.\ndiff --git a/doc/guides/rel_notes/release_16_07.rst b/doc/guides/rel_notes/release_16_07.rst\nindex 30e78d4..29b8b52 100644\n--- a/doc/guides/rel_notes/release_16_07.rst\n+++ b/doc/guides/rel_notes/release_16_07.rst\n@@ -47,6 +47,7 @@ New Features\n * Dropped specific Xen Dom0 code.\n * Dropped specific anonymous mempool code in testpmd.\n \n+* **Added new poll-mode driver for ThunderX nicvf inbuit NIC device.**\n \n Resolved Issues\n ---------------\n", "prefixes": [ "dpdk-dev", "v5", "24/25" ] }
