How to run netmap on ixgbe Virtual Function on Debian 8 Jessie

UPDATE: folks, please be AWARE! In this mode netmap working only in single-copy mode and will not work enough fast (1-2 mpps is a limit). For full support we need another patch for ixgbevf driver.

If you want zero copy support, please poke netmap guys here: https://github.com/luigirizzo/netmap/issues/63

First of all, install Netmap and ixgbe module: http://www.stableit.ru/2014/10/netmap-debian-7-wheezy-intel-82599.html

Please add this code to /etc/rc.local (please remove -e flag from /bin/sh in first line of /etc/rc.local):
insmod /usr/src/netmap/LINUX/netmap.ko
modprobe mdio
modprobe ptp
modprobe dca
insmod /usr/src/netmap/LINUX/ixgbe/ixgbe.ko max_vfs=2,2
insmod /lib/modules/3.16.0-4-amd64/kernel/drivers/net/ethernet/intel/ixgbevf/ixgbevf.ko
And reload server!

 Then, I have physical NIC eth6 which represented as 2 virtual NICs (ip link show):
8: eth6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 90:e2:ba:4a:d8:e8 brd ff:ff:ff:ff:ff:ff
    vf 0 MAC 90:e2:ba:55:aa:bb, spoof checking on, link-state auto
    vf 1 MAC 90:e2:ba:55:bb:cc, spoof checking on, link-state auto
15: eth10: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 90:e2:ba:55:aa:bb brd ff:ff:ff:ff:ff:ff
16: eth11: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 90:e2:ba:55:bb:cc brd ff:ff:ff:ff:ff:ff
Then, I configure MAC's for both virtual functions:
ip link set eth6 vf 0 mac 90:e2:ba:55:aa:bb
ip link set eth6 vf 1 mac 90:e2:ba:55:bb:cc
And reload ixgbevf driver (required for configuration):
rmmod ixgbevf
modprobe ixgbevf
After this operations all interfaces become ready:
ethtool eth6
