It's really helpful to improve community collaboration. I'm sure it's going to generate some interesting discussions. Please take care to discuss such announce on dev list only. The announce@dpdk.org list is moderated to keep a low traffic. I would like to open discussion about a really important feature, showed last week by John Fastabend and John Ronciak during LinuxCon: > Bifurcated Driver: With the Bifurcated Driver, the kernel will retain > direct control of the NIC, and will assign specific queue pairs to DPDK. > Configuration of the NIC is controlled by the kernel via ethtool. This design allows to keep the configuration code in one place: the kernel. In the meantime, we are trying to add a lot of code to configure the NICs, which looks to be a duplication of effort. Why should we have two ways of configuring e.g. flow director? Since you at Intel, you'll be supporting your code, I am fine for duplication, but I feel it's worth arguing why both should be available instead of one. -- Thomas
