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

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.

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

It seems the DPDK function rte_eth_dev_get_port_by_name() will always return 
the port ID of the first port on your NIC, when you specify the single PCI 
address and that's where the problem is. There doesn't seem to be a way 
currently to indicate to the calling application that in fact two (or more) 
port IDs are associated with the one PCI address.

I am cc-ing DPDK users mailing list for hopefully some input. Are there any 
plans for the rte_eth_dev_get_port_by_name function to be compatible with NICs 
with multiple ports under the same PCI address?

Thanks,
Ciara

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 ?
