It was never a substitute for proper locking, and its use has been replaced with internal spinlocks. We will cover this topic thoroughly later in this chapter in “Transmission Timeouts”. Used for end of life products. Whatever numbers you choose, you can correctly set up the interfaces for operation by issuing the following commands:. The numbers you choose might be real Internet or intranet numbers, and assigning them to your interfaces will prevent communication with the real hosts. The interface is stopped when it is brought down; operations performed at open time should be reversed.

This capability can be used by the system administrator if the interface cannot be probed for. For example, pppstats uses device-specific commands to retrieve information from the ppp interface driver.
The networking subsystem has seen many changes over the years as the kernel developers have striven to provide the best performance possible. Finally, the driver updates its statistics counter to record that a packet has been received. The kernel interface for network drivers is designed for this different mode of operation. Operations that can be performed on network interfaces are listed in this section.
Most networking technologies involving an actual, physical connection provide a carrier state; 82574ti presence of the carrier means that the hardware is present and ready to function. This specific part is no longer being manufactured or purchased and no inventory is available.

This sort of problem is common with some devices designed to run on personal computers. Although it is possible to write polling drivers, and a few exist in the official 82574iit, interrupt-driven operation is much better, both in terms of data throughput and computational demands. The type of the name field in struct device was different. It was never a substitute for proper locking, and its use has been replaced with internal spinlocks.
If the driver needs to do anything particular when the MTU is changed, it should declare its own function; otherwise, the default will do the right thing. The usual warning applies here: This method oinux the entry point for configuring the driver.
This is a consequence of the internal workings of the interface — snull has to look inside and interpret the packets to properly emulate a pair of hardware interfaces. Most took the form of small changes to function prototypes, rather than sweeping changes to the network code as a whole.
The return value points to the data space just created. The driver won’t need to use this function, but it is included here for completeness.
Your comments have been sent. In both cases only the source file Space. The actual definition of the structure is introduced at the end of this section. To simplify the discussion, the interface uses the Ethernet hardware protocol and transmits IP packets. This section discusses the design concepts that led to the snull network interface. What is the difference between Boxed and Tray Processors?
If yours is something radically new and different, however, you will 825774it to assign the following fields by hand. If initialization fails, the structure is not linked to the global list of network devices.

The return value from the function is the length of that address. The numbers you choose might be real Internet or intranet numbers, and assigning them to your interfaces will prevent communication with the real hosts.
The field is used in “Initializing Each Device”, later in this chapter. The overhead introduced in this case is acceptable, because the number of multicast packets on a typical network is low. Packet sniffers such as tcpdump set promiscuous mode on the interface in order to retrieve all packets that travel on the interface’s transmission medium. The kernel handles the job of tracking which multicast addresses are of interest at any given time.
