This file was scheduled to be removed in 2014, but due to its
large number of users it will be sticking around for a bit
longer. Despite it being marked as stabe, the newer "hard" and
"soft" interfaces should be preffered, since it is not possible
longer. Despite it being marked as stable, the newer "hard" and
"soft" interfaces should be preferred, since it is not possible
to express the 'soft and hard block' state of the rfkill driver
through this interface. There will likely be another attempt to
remove it in the future.
