This is the end of mac80211, and device driver will take over.ДЄs mentioned previously, through the mac80211 local->ops->tx, the registered handler in the device driver is invoked. Static const struct ieee80211_ops rt73usb_mac80211_ops = An example of how a WiFi driver (rt73usb) interfaces with mac80211 is: Such transparency is often achieved through function pointers. As another example, adding a new network protocol should ideally not change the codes in socket layer and device agnostic layer. applying a patch, or even adding a new driver for new device), but such changes does not affect the mac80211 block, and we do not need to change the codes in mac80211. For example, we may make some changes in the WiFi driver block (e.g. 1 have clearly defined boundaries, and support transparency, which means what happens in one block should not affect others. Most of the time, the hardware, such as WiFi adapters, deals with majority of PHY and lower MAC operations, and the Linux wireless subsystem largely handles the upper MAC. probing, authentication, and association), and the latter refers to the time critical operations of MAC such as ACK. For a more refined breakdown, the MAC layer can be further divided into upper MAC and lower MAC, where the former refers to the management aspect of the MAC (e.g. The Linux wireless subsystem, together with WiFi devices, deals with the bottom two layers (MAC and PHY) of the OSI model. Our focus here will be on soft MAC devices, as shown in Fig.

Mac80211 is a driver API that supports only software MAC devices.

Both soft MAC and full MAC devices need to work with cfg80211. It also provides management interface between kernel and user space via nl80211. In particular, cfg80211 provides configuration management services in the kernel. Often, we can think of the Linux wireless subsystem to contain two major blocks: cfg80211 and mac80211, and they help the WiFi driver to interface with rest of the kernel and user space. If it is implemented in software, the device is a soft MAC device. If it is implemented in device hardware, the device is a full MAC device. There are two types of WiFi devices, depending on where IEEE802.11 MLME is implemented. On the left are Ethernet devices, and on the right are WiFi devices. The user space applications are running on top of it, and the hardware devices are at the bottom. 1: Overview of Linux wireless networking architecture 1, which should show the high-level blocks in Linux kernel networking, and how Linux wireless fits into the kernel.ДЇig. To begin the walk, letГўв‚¬в„ўs first have an overview of the architecture in Fig. After tracing through the source codes, I put down this summary in the hope that it can be helpful as an overview of how things work in Linux wireless networking. When I started working on Linux wireless, I was lost in the immense code base, and I was looking for an introductory material that can answer high-level questions like above. How does Linux wireless interface with the kernel? How are packets transmitted / received?
