[dpdk-dev] Intel fortville not working with multi-segment
Hi, I am using PF pass-through and it doesn't work even with 2000 bytes of server response page size. Looks like the first segment of each session is not received. When i am changing the server response size to 1000 bytes, all works as expected. I am working with dpdk 1.8 version. Any idea why ? Is it related to i40e multi segment support?

For PF pass-through, you might have already gotten the fix. For VF pass-through, there is a bug fix which is needed for supporting jumbo frame and multiple mbuf. http://www.dpdk.org/dev/patchwork/patch/4641/ Regards, Helin > -Original Message- > From: dev [mailto:dev-bounces at dpdk.org] On Behalf Of Nissim Nisimov > Sent: Monday, May 11, 2015 3:48 AM > To: Nissim Nisimov; 'dev at dpdk.org' > Subject: Re: [dpdk-dev] Intel fortville not working with multi-segment > > Hi, > > can someone assist regarding this issue? > > Is it a known limitation in i40e/dpdk (no support for multi-segment)? > > Thx > Nissim > > -Original Message- > From: dev [mailto:dev-bounces at dpdk.org] On Behalf Of Nissim Nisimov > Sent: Thursday, May 07, 2015 5:44 PM > To: 'dev at dpdk.org' > Subject: [dpdk-dev] Intel fortville not working with multi-segment > > Hi, > > > > I am trying to work with Intel Fortville (XL710) NICs in Passthrough mode > from a VM running dpdk app. > > > First I didn't have any TX traffic from the VM, I got dpdk patch for this > issue > and it fixed it.

Hi Nissim Are you using PF pass-through or VF pass-through? For PF pass-through, you might have already gotten the fix.

Hi, can someone assist regarding this issue? Is it a known limitation in i40e/dpdk (no support for multi-segment)?
