Hello,
Thanks for the information. I think the rc.conf(5) manual page needs =
updating as well for FreeBSD 10. It now says:
gif_interfaces
(str) This variable is deprecated in favor of
cloned_interfaces. Set to the list of gif(4) tunnel =
inter=E2=80=90
faces to configure on this host. A =
gifconfig_=E2=9F=A8interface=E2=9F=A9
variable is assumed to exist for each value of =
interface.
The value of this variable is used to configure the =
link
layer of the tunnel according to the syntax of the =
tunnel
option to ifconfig(8). Additionally, this option =
ensures
that each listed interface is created via the create =
option
to ifconfig(8) before attempting to configure it.
This should be reworded so that it says that gifconfig_<interface> is =
also a deprecated variable and also mention that it does not work with =
cloned_interfaces (the reason for my PR). Also it should be mentioned =
that the proper way to configure the tunnel part of the gif(4) interface =
is to use ifconfig_gifN=3D=E2=80=9Ctunnel my.ip their.ip=E2=80=9D. Maybe =
it=E2=80=99s also worth repeating the information in the gif(4) manual =
page?
