Hi Rami, From: Rami Rosen [mailto:ramir...@gmail.com] Sent: Tuesday, April 16, 2019 5:55 AM To: Lu, Wenzhuo <wenzhuo...@intel.com> Cc: dev@dpdk.org Subject: Re: [dpdk-dev] [PATCH] doc: update ICE doc
Hi, In I40E DPDK nic guide, https://doc.dpdk.org/guides/nics/i40e.html, MDD does not appear. [Wenzhuo] As I know, this feature is not supported by i40e. I40e can send such packets. That’s why we want to mentions this different behavior for ice. In IXGBE DPDK nic guide, https://doc.dpdk.org/guides/nics/ixgbe.html, MDD appears, but in the known issues section. [Wenzhuo] Actually, for ixgbe, we want to mention MDD as a limitation (the same section as known issue). Because it’s more like our driver’s robust is not so strong. We have to ask the APP to provide the right L2/L3 length. (The reason is it’s not effective to let the driver inspect the packet to get the right length.) But this ice behavior is more like a feature. To my opinion, it’s reasonable to drop such packets. That’s why I put it in the feature section. I think MDD is supported on both. just wonder, for the sake of consistency, is it worth to add such a section also for these nics ? Other than that, Acked-by: Rami Rosen <ramir...@gmail.com<mailto:ramir...@gmail.com>>
