100GbE Intel Wired LAN Driver Updates 2021-10-20

Sudheer Mogilappagari says:

This series introduces initial support for Application Device Queues(ADQ)
in ice driver. ADQ provides traffic isolation for application flows in
hardware and ability to steer traffic to a given traffic class. This
helps in aligning NIC queues to application threads.

Traffic classes are configured using mqprio framework of tc command
and mapped to HW channels(VSIs) in the driver. The queue set of each
traffic class is managed by corresponding VSI. Each traffic channel
can be configured with bandwidth rate-limiting limits and is offloaded
to the hardware through the mqprio framework by specifying the mode
option as 'channel' and shaper option as 'bw_rlimit'.

Next, the flows of application can be steered into a given traffic class
using "tc filter" command. The option "skip_sw hw_tc x" indicates
hw-offload of filtering and steering filtered traffic into specified TC.
Non-matching traffic flows through TC0.

When channel configuration are removed queue configuration is set to
default and filters configured on individual traffic classes are deleted.

example:
$ ethtool -K eth0 hw-tc-offload on

Configure 3 traffic classes and map priority 0,1,2 to TC0, TC1 and TC2
respectively. TC0 has 2 queues from offset 0 & TC1 has 8 queues from
offset 2 and TC2 has 4 queues from offset 10. Enable hardware offload
of channels.

$ tc qdisc add dev eth0 root mqprio num_tc 3 map 0 1 2 queues \
        2@0 8@2 4@10 hw 1 mode channel

$ tc qdisc show dev eth0
qdisc mqprio 8001: root  tc 2 map 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 0
             queues:(0:1) (2:9) (10:13)
             mode:channel

Configure two filters to match based on dst ipaddr, dst tcp port and
redirect to TC1 and TC2.
$ tc qdisc add dev eth0 clsact

$ tc filter add dev eth0 protocol ip ingress prio 1 flower\
  dst_ip 192.168.1.1/32 ip_proto tcp dst_port 80\
  skip_sw hw_tc 1
$ tc filter add dev eth0 protocol ip ingress prio 1 flower\
  dst_ip 192.168.1.1/32 ip_proto tcp dst_port 5001\
  skip_sw hw_tc 2

$ tc filter show dev eth0 ingress

Delete traffic classes configuration:
$ sudo tc qdisc del dev eth0 root
