Hi, At mempool creation time you can pass in a callback function to rte_mempool_create() that DPDK will call for every mbuf on the mempool so you can initialize them to your liking. However, there doesn't seem to be a straight forward way do that again once the mempool is already created though.
I'm wondering if there's a clean/nice way to re-initialize all mempool's mbufs once the mempool's been created? I was thinking on something like retrieving all mbufs one by one, do my re-initialization and then put them back into the mempool. I'd have to make sure of getting all mbufs out before start putting them back again to avoid the cache, but that'd be OK. Of course this won't be on the fast-path. Is there a cleaner way to do this? Any suggestion? Thanks, Nico. -- Nicol?s Pernas Maradei Software Engineer Emutex Ltd.
