change the way of what ppp submits to the RADIUS server as NAS-Port-Id. Possible options are: the PID of the process owning the corresponding interface, tun(4) interface number, interface index (as it would get returned by if_nametoindex(3)), or it's possible to keep the default behavior. Check the ppp(8) manual page for details. PR: bin/112764 Submitted by: novel (myself) Reviewed by: flz Approved by: flz MFC after: 1 month
