Thanks Thomas and Neil. Sadly, no joy. While I generally like gmail for my mail, there's not a reasonable way to import the mbox file or to control the message id. If someone else wants to resend the message to the list, I can reply to that. Otherwise, here are the relevant bits from the original patch email: From patchwork Wed Jul 23 06:45:12 2014 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [dpdk-dev] kni: optimizing the rte_kni_rx_burst From: Hemant Agrawal <Hemant@freescale.com> X-Patchwork-Id: 84 Message-Id: <14060979121185-git-send-email-Hemant@freescale.com> To: <dev@dpdk.org> Date: Wed, 23 Jul 2014 12:15:12 +0530 The current implementation of rte_kni_rx_burst polls the fifo for buffers. Irrespective of success or failure, it allocates the mbuf and try to put them into the alloc_q if the buffers are not added to alloc_q, it frees them. This waste lots of cpu cycles in allocating and freeing the buffers if alloc_q is full. The logic has been changed to: 1. Initially allocand add buffer(burstsize) to alloc_q 2. Add buffers to alloc_q only when you are pulling out the buffers.

We saw the same behavior in our app and ended up avoiding it higher in the stack (in our code).

You can't use the web interface for this. Enable imap access to your gmail account, and setup an MUA like mutt to point to it. Then the mutt client can open the mbox file, or you can fill out the in-reply-to: header manually. Neil

Honestly, while I was happy to do the review since I've been digging into KNI anyway, I'm not going to spend time setting up an MUA just for this. Jay

But if you ever want to be able to respond to an email you've deleted, you need an MUA that can import mbox files from an archive, or at least allow editing of header fields. FWIW, its not hard to do, heres a redacted version of my gmail .muttrc file: set folder=imaps://<my email address>@imap.gmail.com set spoolfile=imaps://<my email address>@imap.gmail.com/INBOX set ssl_starttls=yes set editor=vi set sort=threads set smtp_url=smtps://<my email address>@smtp.gmail.com set from="Neil Horman <my email address>"
