Probably you added it to an Open vSwitch bridge some funny way? What does "ovs-dpctl show" print? How about "brctl show"?

I'd suggest having the controller submit a flow stats request every 2 seconds. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] libnuma missing FreeBSD 11.1
Hello, I'm trying to build Open vSwitch by following this guide : http://docs.openvswitch.org/en/latest/intro/install/dpdk/ uname -a gives : FreeBSD 11.1-RELEASE-p9 In the guide I skipped the part for installing DPDK from source and followed this guide instead : https://dpdk.org/doc/guides/freebsd_gsg/install_from_ports.html Everything runs fine until I try to run ./configure --with-dpdk=/usr/local/share/dpdk/x86_64-native-bsdapp-clan/lib in ovs folder. I get the following error : Non relevant output from ./configure checking target hint for cgcc... x86_64 checking whether dpdk datapath is enabled... yes checking for library containing get_mempolicy... no configure: error: unable to find libnuma, install the dependency package I guess this error message is intended to linux users because searching on the web libnuma+freebsd returns no package or port to install on FreeBSD. Instead I found that numactl was available since FreeBSD 11.0. ./configure end correctly without --with-dpdk option What can I do to fix this? thanks, Florian___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

If you make handle_flow_stats_request() block, then nothing else will get handled. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
