Based on original patches by Rusty Russell, Thomas Huth and Cornelia Huck. Note: at this time, we do not negotiate this feature bit in core, drivers have to declare VERSION_1 support explicitly.
After all drivers are converted, we will be able to move VERSION_1 to core and drop it from all drivers. Signed-off-by: Michael S.
