Hello,
I'm playing littlebit with ingress policing in openvswitch and I found some
kind of inconsistency.
In docs and in source code (https://github.com/openvswitch/ovs/blob/master/
lib/netdev-linux.c#L4698) there is info that burst is set in kilobits, but I
found that in fact it is set in kilobytes in tc.
So long story short:
root@ubuntu-1604-test:/home/ubuntu# ovs-vsctl show
f0d1f90d-174f-47bf-89bc-bf37f2da0271
Bridge "br1"
Port vethA
Interface vethA
Port "br1"
Interface "br1"
type: internal
ovs_version: "2.5.0"
root@ubuntu-1604-test:/home/ubuntu# ovs-vsctl set Interface vethA
ingress_policing_rate=1000 -- set Interface vethA ingress_policing_burst=100
root@ubuntu-1604-test:/home/ubuntu# ovs-vsctl list interface vethA | grep
ingress
ingress_policing_burst: 100
ingress_policing_rate: 1000
results in:
root@ubuntu-1604-test:/home/ubuntu# tc filter show dev vethA parent ffff:
filter protocol all pref 49 basic
filter protocol all pref 49 basic handle 0x1
police 0x1 rate 1Mbit burst 100Kb mtu 64Kb action drop overhead 0b
ref 1 bind 1
As You can see above, burst is given in "Kb" units what, according to tc man
(http://lartc.org/manpages/tc.txt) means kilobytes.
So question: is it intentional inconsistency or bug? If bug then where: in
code or in docs?
