X25: Add if_x25.h and x25 to device identifiers
V2 Feedback from John Hughes. - Add header for userspace implementations such as xot/xoe to use - Use explicit values for interface stability - No changes to driver patches V1 - Use identifiers instead of magic numbers for X25 layer 3 to device interface. - Also fixed checkpatch notes on updated code. [ Add new user header to include/linux/Kbuild -DaveM ] Signed-off-by: Andrew Hendry <andrew.hendry@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
