Enable promiscuous and allmulticast mode control from the VF using rte_eth_promiscuous_enable()/rte_eth_promiscuous_disable() and rte_eth_allmulticast_enable()/rte_eth_allmulticast_disable(). For promiscuous mode host/PF igb driver should be built with IGB_ENABLE_VF_PROMISC. For allmulticast mode "allmulti" flag should be set for appropriate PF ifconfig eth0 allmulti Signed-off-by: Yury Kylulin <redacted> --- v2 * Added promiscuous mode control * Switching logic is the same like in igb PF driver drivers/net/e1000/igb_ethdev.c | 49 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+)
