Hi Alan, Thanks for this. We are already trying such a modification but not for "spidev" but for "cc120" that we are trying to connect to beaglebone, through "mac802154/iee802154" proto drivers. Not yet successful but still working on. Will soon send our state on the mailing list.
We are a bit "new" to kernel and hardware/protocols drivers in Linux. Why the way is so tricky for us. Do you know a good "tutorial" showing global schemes of interfaces between Network stack / Protocols drivers / hardware drivers ?
