Hi Ben:
I have two questions about this function:
Firstly, for some SDN controller (OVN etc.), the arp request is handled by
userspace, that means: When ovs-vswitchd exits, the remaining traffic should
only keep for about 30s as for most linux kernel, every 30s it should send an
arp
Hi Flavio and all:
Is there a way to support software TSO for DPDK tunnel network ? I have
tried userspace TSO function, and running on tunnel network, I have got the
following error:
"Tunneling packets with HW offload flags is not supported: packet dropped"
So is there a way to
Hi Ben:
I have tried, this patch works! Thank you!
One question: should "simap_destroy(>tnl_backers)" be within the
close brace ?

Hi Ben:
I have read your patch about "not delete datapath flow when daemon exit". I
think this patch is really important, It can be used during upgrading without
effecting existing traffic. I have test in my env, and found it works! Thanks a
lot !
But I have a question about tunnel
Hi Ben && all:
I have read your recently patch about "ovsdb-server: Allow OVSDB clients to
specify the UUID", as far as I know, this patch has solved specifing uuid by
adding "uuid" in jsonrpc transaction. But if I want to use xxxctl tool to
create table, the uuid still can't be specified.
Hi Flavio:
From userspace-tso.rst I have found this version doesn't support TSO
over VxLAN, the reason is DPDK pmd driver can't add tunnel header for
segmentation packet ? Also, do you have plan to backport userspace tso function
into version 2.10 ?
Thanks

Hi all:
I have been testing OVS-DPDK Rate limit using meter table these days, but I
have found the rate deviation is larger than kernel meter. My test result is as
below:
case 1. No Rate limit : Iperf between two VMs(on the same compute node) TCP
bandwidth is above 1G
case 2. Rate
Hi all:
Currently OVS maintains several Statistics counters per interface.
"rx_missed_errors" counter is amount them and collects pkts not received due to
local resource constaints. Many ovs netdevs support collecting this counter,
such as netdev-linux, netdev-dpdk, netdev-bsd and so on.

Re: [ovs-dev] Re：Question about ovs-tcpundump
The packet is not needed for most purposes (a few exceptions are in the
documentation), but if you supply it you don't have to specify all of
the field values by hand.

Hi Aaron:
Perfect Answer! Thanks very much !!
I have another question: how could the result of ovs-tcpundump get used in
ofproto/trace ? From the document ovs-vswitchd I have found the ofproto/trace
command shoud be formatted as "dpname + odp_flow + packet", but it seems the
dpname +
