As already stated the PPS RFC doesn't use ioctls to manage PPS data so
we can modify ioctls according our needs!

In fact we can modify the LinuxPPS wrapper functions to still remain
RFC compliant. :)

In this scenario I think we can do as Andrew suggests modifying
LinuxPPS docs accordingly... maybe we can add a new file into
linux/Documentation/pps directory describing Linux PPS ioctls and how
they interact with PPS RFC functions.

Andrew, could this be an acceptable solution?

Ciao,

Rodolfo
