After that it reported that the fw is up to date. After all that - still no drop counters when packets are dropped... /Arnon On Thu, Oct 22, 2015 at 3:48 PM, Eimear Morrissey < eimear.morrissey@ie.ibm.com> wrote: > Arnon Warshavsky wrote on 10/22/2015 12:12:47 PM: > > > From: Arnon Warshavsky > > To: Eimear Morrissey/Ireland/IBM@IBMIE > > Cc: dev@dpdk.org > > Date: 10/22/2015 12:12 PM > > > Subject: Re: [dpdk-dev] Inconsistent statistics counters for pmd_i40e > > > > You are right. > > Given this thread updated today > > http://dpdk.org/ml/archives/dev/2015-September/023480.html (updates > > from today still not there) > > It seems I was too quick to jump to conclusion. > > > Just in case, when bound to i40e, can you run ethtool -i on that > interface? > > It should show the fw version. > > > thanks > > /Arnon > > > > On Thu, Oct 22, 2015 at 12:57 PM, Eimear Morrissey < > > eimear.morrissey@ie.ibm.com> wrote: > > Arnon Warshavsky wrote on 10/19/2015 03:46:22 PM: > > > > > From: Arnon Warshavsky > > > To: Eimear Morrissey/Ireland/IBM@IBMIE > > > Cc: dev@dpdk.org > > > Date: 10/19/2015 03:46 PM > > > > > Subject: Re: [dpdk-dev] Inconsistent statistics counters for pmd_i40e > > > > > > Hi Eimear > > > > > > This is the link I have. > > > https://downloadcenter.intel.com/download/24769 > > > > > > I guess that the version seen in the web page comes from a different > > > parallel universe. > > > You should see the actual fw version inside the zip file. > > > > > Thanks > > > /Arnon > > > > > > On Mon, Oct 19, 2015 at 5:30 PM, Eimear Morrissey < > > eimear.morrissey@ie.ibm.com > > > > wrote: > > > Arnon Warshavsky wrote on 10/19/2015 03:01:46 PM: > > > > > > > From: Arnon Warshavsky > > > > To: Eimear Morrissey/Ireland/IBM@IBMIE > > > > Cc: dev@dpdk.org > > > > Date: 10/19/2015 03:01 PM > > > > Subject: Re: [dpdk-dev] Inconsistent statistics counters for pmd_i40e > > > > > > > > > > > Hi Eimear, > > > > > > > > I just experienced the same problem with firmware versions 4.23 and > > > > 4.33 (dpdk 2.0).
