Build Update for horms2/ovs
-------------------------------------

Build: #213
Status: Passed

Duration: 1 hr, 16 mins, and 16 secs
Commit: d702652 (topic/pieter/ingress-rate-limiting-rfc-v3)
Author: Pieter Jansen van Vuuren
Message: lib/tc: add ingress ratelimiting support for tc-offload

Firstly this patch introduces the notion of reserved priority, as the
filter implementing ingress policing would require the highest priority.
Secondly it allows setting rate limiters while tc-offloads has been
enabled. Lastly it installs a matchall filter that matches all traffic
and then applies a police action, when configuring an ingress rate
limiter.

An example of what to expect:

OvS CLI:
ovs-vsctl set interface <netdev_name> ingress_policing_rate=5000
ovs-vsctl set interface <netdev_name> ingress_policing_burst=100

Resulting TC filter:
filter protocol ip pref 1 matchall chain 0
filter protocol ip pref 1 matchall chain 0 handle 0x1
  not_in_hw
	action order 1:  police 0x1 rate 5Mbit burst 125Kb mtu 64Kb
action drop/continue overhead 0b
        ref 1 bind 1 installed 3 sec used 3 sec
        Action statistics:
        Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
        backlog 0b 0p requeues 0
