Re: [vpp-dev] Query for IPSec support on VPP

I was just reproducing your steps. Check that you have created a 'vdev crypto_aeasni_mb0' in /etc/vpp/startup.conf inside the 'dpdk' section. Then to check if you have support, you can run: vppctl show crypto device mapping verbose Thanks, Sergio On 30/08/2017 13:07, Mukesh Yadav

Re: [vpp-dev] About the order of  VLIB_INIT_FUNCTION called between different plugins

Yes, also please note that you can at any time use vlib_get_plugin_symbol(..) function to get pointer to symbol in another plugin. If you get NULL then another plugin is not loaded. So something like this should work, assuming that you want to go that way... static clib_error_t * bar_init

Re: [vpp-dev] Issue forwarding TCP packets

This is a system problem; vpp can’t solve it all by itself. When forwarding packets at L2, vpp doesn’t look past the ethernet header. It’s simply delivering packets generated by the Linux kernel on one interface to another Linux kernel interface. The kernel cheats by not generating L4

Re: [vpp-dev] Issue forwarding TCP packets

Hi Florin, For now we can proceed with a requirement to disable offload on VMs. but still keeping performance in view i think VPP should have option similar to linux bridge to be able to do forwarding without correct checksums, while offloading is enable the real checksum calculations should be

Re: [vpp-dev] https://gerrit.fd.io/r/#/c/8236/

To me, it doesn't seem to be a crime to add bc to the dependencies. I guess another approach would be to remove the dot in 16dot04 and then just use shell arithmetic. The release numbers are always in the same format, 2 digits DOT 2 digits, so I would think that should work. Burt On Wed, Aug 30,

Re: [vpp-dev] Dynamically change number of cores used by VPP?

AFAIK there is no support to adjust the number of cores used or the cores frequency in runtime. Not sure if there is full support to dynamically switch between polling and interrupt mode, but I believe most of the infra is already there (read below thread).

Re: [vpp-dev] Query for IPSec support on VPP

Which VPP are you using? If you are using/installing VPP package (rpm/deb), then it is likely that you do not have DPDK SW crypto support. As a summary, if you want DPDK SW crypto support: - VPP package: 17.07.1 (AFAIK not released yet) or newer. - From source: - 17.04 or 17.07: need to

Re: [vpp-dev] https://gerrit.fd.io/r/#/c/8236/

Hi, This probably is be because you don't have bc. It is not in the dependency list. I'm so used to having it around that I did not think to check. Sorry. If so, the best thing probably is to revert and not to increase the dependency list just to silence a warning. Regards, -- Gabriel
