Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 



Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2018-02-14

This patch series enables the new mqprio hardware offload mechanism
creating traffic classes on VFs for XL710 devices. The parameters
needed to configure these traffic classes/queue channels are provides
by the user via the tc tool. A maximum of four traffic classes can be
created on each VF. This patch series also enables application of cloud
filters to each of these traffic classes. The cloud filters are applied
using the tc-flower classifier.

Example:
    1. tc qdisc add dev vf0 root mqprio num_tc 4 map 0 0 0 0 1 2 2 3\
        queues 2@0 2@2 1@4 1@5 hw 1 mode channel
    2. tc qdisc add dev vf0 ingress
    3. ethtool -K vf0 hw-tc-offload on
    4. ip link set eth0 vf 0 spoofchk off
    5. tc filter add dev vf0 protocol ip parent ffff: prio 1 flower dst_ip\
        192.168.3.5/32 ip_proto udp dst_port 25 skip_sw hw_tc 2
