I think that's a good approach.


Seems fine to me
One alternative since I remember there was some confusion about the portid 
context before.

dpdk-dpdkportid=dpdk0  ?


That is probably to many ‘dpdk’s; let me change the alternative to

options:dpdk-dpdkportid=0  ?

There was no response when I cross-posted to DPDK users mailing list, 
so I can't confirm.

Seems like a good idea to take in the port number as a workaround. If
it's just temporary because there will be a fix in DPDK sometime, then
perhaps a new experimental option could be introduced  (e.g.
dpdk-legacyname or dpdk-dpdkportnum) and removed in time. Otherwise
dpdk-devargs usage will be changing between releases, break backwards

The workaround discussed is a patch to enable backwards compatibility with the 
old port IDs. Something like the following:

– set Interface portX options:dpdk-devargs=dpdkportid0

Looking for input.

Were you able to confirm those addresses by running ./dpdk-devbind.py -s
in your /tools dir?

On running dpdk-devbind.py --status , I can see the ConnectX-3 pro NIC, having 
only one PCI address.

Hi Devendra

Could you please respond to Kevin’s query just to be sure ?

Were you able to confirm those addresses by running ./dpdk-devbind.py -s
in your /tools dir?

Thanks Darrell

Hi,

I have compiled and built ovs-dpdk using DPDK v17.08 and OVS v2.8.0. The
NIC that I am using is Mellanox ConnectX-3 Pro, which is a dual port 10G
NIC. The problem with this NIC is that it provides only one PCI address for
both the 10G ports.

So when I am trying to add the two DPDK ports to my br0 bridge

# ovs-vsctl --no-wait add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk
options:dpdk-devargs=0002:01:00.0

# ovs-vsctl --no-wait add-port br0 dpdk1 -- set Interface dpdk1 type=dpdk
options:dpdk-devargs=0002:01:00.0

The port dpdk1 is added successfully and able to transfer data, but adding
dpdk0 to br0 fails:

With OVS v2.6.1 I never had this problem as dpdk-devargs was not mandatory
and just specifying port name was enough to add that port to bridge.

Is there a way to add port both ports to bridge ?
