Phonet: hook resource routing to userspace via ioctl()'s
I wish we could use something cleaner, such as bind(). But that would not work since resource subscription is orthogonal/in addition to the normal object ID allocated via bind(). This is similar to multicasting which also uses ioctl()'s. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
