Jul 07, 2016 · The Linux networking stack has a limit on how many packets per second it can handle. When the limit is reached all CPUs become busy just receiving packets. In that case either the packets are dropped or the applications are starved of CPU.
Linux kernel stack technologies such as eBPF and the Traffic Classifier hold the promise of allowing SmartNIC vendors like Netronome to stick to the Linux kernel networking stack and allow data The linux networking stack is a big piece of the kernel and you need to spend some time studying it. I think that this books may help (Focused on older kernels 2.4 and 2.6, but the logic remain the same for the latest kernels 3.x): Thanks for contributing an answer to Unix & Linux Stack Exchange!

However, modern enterprise storage systems are The Linux networking stack has changed significantly since ifconfig's heyday -- you will miss information on today's networks if working with ifconfig. The ip command was introduced to manage all aspects of Linux network configuration as the stack changed, and development on the ifconfig command was discontinued.
