FM10K PMD driver only manages host interfaces. For the switch +component, another switch driver has to be loaded prior to FM10K PMD driver. +The switch driver either can be acquired by Intel support or from below link: +https://github.com/match-interface + +CRC strip +FM10000 family always strip CRC for every packets coming into host interface. +So, CRC will be stripped even (struct rte_eth_conf).rxmode.hw_strip_crc is set +to 0. + +Max packet length +FM10000 family support maximum of 15K jumbo frame. The value is fixed and can't +be changed. So, even (struct rte_eth_conf).rxmode.max_rx_pkt_len is set to a value +other than 15364, the frames with 15364 byte still can reach to host interface. + + diff --git a/doc/guides/nics/index.rst b/doc/guides/nics/index.rst index 7bf2938..4f2cc6c 100644 --- a/doc/guides/nics/index.rst +++ b/doc/guides/nics/index.rst @@ -51,6 +51,7 @@ Network Interface Controller Drivers virtio vmxnet3 pcap_ring + fm10k **Figures** -- 1.7.7.6
