Hi. I hunted down and fixed a bug that caused /usr/sbin/usernetctl
not to detach after a ppp connection has benn successuflly established.
I'm using initscripts-4.84-1 (rawhide).

It is a bug in /usr/src/redhat/BUILD/initscripts-4.84/src/ppp-watch.c
(/sbin/ppp-watch), in interfaceStatus(): The error return code of socket()
is -1, not 0.

(Also, the man page says, the protocol family should be specified by a
macro beginning with "PF_", not "AF_". But the PF_... are defined as the
AF_... Is this portable?)

Here is the patch:

      memset(&ifr, 0, sizeof(ifr));
