Adding new protocol to linux.

[Daniel.]

Hi everybody,

I'm planing to write a socket API for Nordic's nRF24L01+ and I was
digging on socket code and find all supported protocols at
include/linux/socket.h with all that #define AF_x y. So my questions
are:

1) Is it possible to write a new protocol for linux with an out of
tree module without modifing socket.h file?
2) Could netlink socket be used to solve this? .. and
3) I saw that there is net_device_ops and proto_ops. How they are tied together?

Thanks in advance and
Best regards,
