Hi Stephen,

Thanks for the feedback.  IMHO overloading the [SOL_SOCKET]
SO_PRIORITY  sockoption for something as different as changing the
mesh-ttl is quite a stretch.   But I admit that it meets the driver
requirements of "never add sockopt" and "not [ab]use netfilter hooks".
 If that's acceptable to all, I'll modify the patch in that direction.

Cheers,

Javier
