Hi,
I am trying to test hardware offloading feature in OVS using
a 2*25G
mellanox NIC. My test setup has static OVS L2 rules to
forward packets
between these two ports. The traffic generators are
connected to these
ports to pump in traffic.
The hardware offloading is enabled in the system by using,
ovs-vsctl --no-wait set Open_vSwitch .
other_config:hw-offload=true
I didnt set any hw-policy explicit, as I kept it default as
'None'
I noticed that when I am sending traffic to these ports,
there are no
rules that are getting programmed into the hardware. Also
there are no
error reported in ovs-vswitchd.log as such.
Of Course the packets are getting forwarded in software. Is
there
anything else needs to be done to make the TC for
programming the
mellanox NICs?

Hi Sugo,
Since you do not have errors in the log did you check if the rules
were added to tc software?
you can dump like this:
# tc -s filter show dev ens5f0 ingress
I dont see any rules that are configured with above tc dump.
then nothing went to the HCA because even if the HW doesn't
support it the rule should be in tc software.
You need to enable the offload feature on the HCA with ethtool.
example:
# ethtool -K ens5f0 hw-tc-offload on
This is enabled .
I am trying to forward traffic between two PFs on the same NIC?
Does it supported in the offload implementation?
offload between PF ports is currently not supported.
only PF and its VFs.
When creating the switchdev on PFs with 2 VFs, there is no VF
netdevs are populated in my system. They are still showing as the
vfs under the PF.
Ofcourse there are no errors too.
Also the system reports the mode 'inline-mode transport'is unsupported.
I am using ubunutu 17.04 with 4.10 kernel.
Is there anything I am missing here?
Any help is really appreciated!.
[Sugu] Some more details on this. I was really getting error when trying
to enable hw-offload on mlnx-4 NICs.
Didnt notice in the logs before.
This the error info that I got from mellanox git.
BAD_SYS_STATE | 0x368B01 | query_vport_counter: vport is not enabled
(INIT_HCA is required)
executing which command raised this error?
I verfied that the ports named eth1, eth2, eth3 and et4 are created for
my vfs, when
I ran the commands 'devlink dev eswitch set pci/0000:07:00.0 mode
switchdev' and
'devlink dev eswitch set pci/0000:07:00.1 mode switchdev'
The detailed error in dmesg are given below,
[ 1245.941287] mlx5_core 0000:07:00.0: mlx5_cmd_check:697:(pid 3107):
QUERY_VPORT_COUNTER(0x770) op_mod(0x0) failed, status bad system
state(0x4), syndrome (0x368b01)

Please note I couldn't run the "inline-mode transport" command as its
not supported.
maybe you need newer iproute package. try to install latest upstream.
We still need to work on docs for this feature but for now I
documented it a little here:
