Re: [ovs-discuss] hardware offloading in ovs-2.8

2017-11-07 Thread 王嵘

For now, I 'm using the "NetXtreme II BCM57810 10 Gigabit Ethernet 168e".
Another question,  I found  ovs-dpdk can't bind this NIC. But I find there is 
the support code for 57810 in the DPDK Bnx2x.
I'm puzzled.
Can you tell me whether  ovs-dpdk support this NIC?

Thanks very much!

Do you have a supported NIC?  This feature is currently for a particular
model of Mellanox NICs.

Re: [ovs-discuss] pmd-cpu-mask/distribution of rx queues not working on windows

Hi Alin, the queues are sorted by measured rxq cycles since
79da1e411ba5. In this test case the rxq cycles are equal for all queues.

On Linux, the sort result is 0,1,3,4,5,6,7,8,9 whereas you are seeing
1,3,4,5,6,7,8,9,0. This impacts the distribution to PMDs and that's
causing the test fail.

Currently the comparison function (rxq_cycle_sort) selects a winner when
they are equal. I have submitted a patch which (amongst other things)
changes that so it will just report they are equal. I've sent a v2,
https://patchwork.ozlabs.org/patch/835385/ can you try that and see if
it fixes the issue on Windows?

thanks,
Kevin.

For some reason openstack was creating tap interfaces on compute with an

[ovs-discuss] OVN patch port for localnet can't be created

2017-11-07 Thread Hui Xiang

Hi folks,

  When I am running ovn in one of my node having the gateway port connected
external network via localnet, the patch port can't be created between
br-ex(set by ovn-bridge-mappings) with br-int, after gdb, it seems the
result get from SBREC_PORT_BINDING_FOR_EACH (binding, ctx->ovnsb_idl)
doesn't include 'localnet' binding type, however it does exist from
ovn-sbctl list port_binding, either I am missing any configuration to make
it work or this is a bug.

  Please have a look and thank much.
