Boost Network Efficiency with Net_Dev Passthrough in Linux Kernel

This chapter describes how the network interfaces fit in with the rest of the Linux kernel and provides examples in the form of a memory-based modularized ... The net_failover driver provides an automated failover mechanism via APIs to create and destroy a failover master netdev and mananges a primary and standby ... If you are curious how exactly this works, please see the Linux kernel's DMA API HOWTO. It turns out the number and size of the RX queues ... Network device structures need to persist even after module is unloaded and must be allocated with alloc_netdev_mqs() and friends. Earlier versions of Linux (2.6.32 in this example) use different structure called inet_sock : ... netdev.transmit netdev.hard_transmit. Receiving ... ... pass the intel iommu=on command-line argument to the kernel ... You may need to pass pci=assign-busses to Linux at boot (see the above example. ReiserFS file system option has been disabled​. Since ReiserFS is scheduled to be removed from the Linux kernel, the option to format a device with ReiserFS has ... The netdev interface enables any module to register itself as a layer 2 network device in Linux kernel. Each module has to provide the ability ... All other members of the structure may share memory. Ioctls If an ioctl is marked as privileged, then using it requires an effective user ID of 0 or the ... A plain ini-style text file that encodes configuration about a virtual network device, used by systemd-networkd(8).
