[dpdk-dev] [PATCH v2] e1000: enable promiscuous and allmulticast support for VF

Tue Feb 9 10:09:43 CET 2016
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

v2
* Added promiscuous mode control
* Switching logic is the same like in igb PF driver
