Re: [vpp-dev] PPPoE plugin documentation/support
Hi Alp Arslan, Since PPPoE control packet is special, which destination MAC is the PPPoE client's MAC. Need to submit a patch to identify it and not perform L3 MAC filter in ethernet-input-inline() function.

The control plane interface is dropping the replies with error "L3 MAC MISMATCH". How do I set the interface to l2? Using the command " set interface l2 bridge 1" is not working, as it starts to drop the PADI packets also.

[vpp-dev] ipsec support for chained buffers.
Hi Is there any plans or any work in progress to extend the support for ipsec encrypt nodes to support the chained buffers?

Yes, it should be easy to cherry-pick into any release where it's needed. HTH...

Check out src/plugins/perfmon/perfmon_periodic.c for one take on that problem...

Is there any mechanism where I can call a function in worker thread from the main thread ? That is, just the reverse of the above. I can use interrupts (vlib_node_set_interrupt_pending) but I can't send any data with the interrupt I suppose. So basically I want to find out if there is any infra available where I can send some data to my worker thread from the main thread instead of creating a frame of data and enqueueing it the normal way to the worker towards a node.
