This patch adds a class driver for raw Ethernet drivers under Xenomai. The goal is to support industrial protocols such as EtherCAT and IEC 61850, where the "stack" is a user space program needing direct access at the packet level. The class driver offers interfaces for registration, buffer management, and packet sending/receiving.
Although this patch is a kind of first draft, still I have it working on the Freescale P2020 with a real world application, with very good results. I can post a patch series for the gianfar driver in the ipipe tree, if anyone is interested. The user space interface is a character device and not a socket, simply because my applications will probably never need fancy socket options. The class driver could surely be made to offer a socket instead, but I think the character is sufficient. The class driver is clearly in the wrong directory within the source tree, but I put it there just to get started. It really does not fit to any of the other drivers, so it probably would need its own place under ksrc/drivers.
