Firmware for Atmel at76c50x wireless networking chips.
The drivers for these chips in the Linux 2.6.x kernel do not include the firmware; this firmware needs to be loaded by the host on most cards using these chips. This package provides the firmware images which should be automatically loaded as needed by the hotplug system. It also provides a small loader utility which can be used to accomplish the same thing when hotplug is not in use.
