Hi, I'm currently working on bringing the gdm72xx WiMAX driver out of staging. The driver currently uses two control channels: 1. The SIOCDEVPRIVATE ioctl to send and receive state messages 2. A customly defined netlink protocol for passing messages verbatim to the device controller AFAIK both of the above are deprecated, so I considered switching to the interface defined in wimax.h, which defines a communication protocol over generic netlink that replaces (2) nicely. However it is not compatible with (1), as: * Except from the device status, the gdm72xx driver uses two more types of messages (connection and OMA status), which is not supported by wimax.h. * The gdm driver needs to be able to receive status messages from userspace, which is not supported by wimax.h either. I therefore consider using the wimax stack as defined in wimax.h for the netlink part, but replacing the ioctl with a file under /sys/class/net/wm0/ My questions are whether the above location would be the right place for that file, and, more importantly, whether this is a generally a valid approach and not just an ugly workaround.
