Dave, Does VPP support the concept of additional threads that are spawned from within a plugin, lets call them 'external threads', and the allocation of a vlib_main_t / vlib_buffer_pool_thread_t for these external threads, or should all interactions such as freeing a buffer, be performed from within the worker thread that the buffer was originally presented to the plugin on..

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> As long as the thread has an associated vlib_main_t / vlib_buffer_pool_thread_t not accidentally shared with another thread, you shouldn't have any problems...

Initial testing indicates that it works. Regards Simon
