Network Interface Bonding shows how individual devices (marked by eth) can be combined to create a bonded device. You can bond eth0 and eth1 into a single virtual interface, bond0, or eth2 and eth3 into bond1, to provide a redundant active/standby interface. The low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard, or is contained into a USB-connected dongle. This kind of functionality is usually referred to as user-level networking. Each receive queue is assigned to a separate interrupt; by routing each of those interrupts to different CPUs or CPU cores, processing of the interrupt requests triggered by the network traffic received by a single NIC can be distributed improving performance.
