[Pkg-utopia-maintainers] Bug#794237: nm upgrade from 9.10.0 to 1.0.6.0-2 breaks my openconnect vpn also

[Brent S. Elmer Ph.D.]

When upgrading my computer, my openconnect vpn broke.  I finally
narrowed it down to upgrading network-manager from the version in
jessie to the version in stretch.  It is network-manager that is
causing the trouble.  When network-manager only is upgraded, when I
connect to my openconnect vpn, the newer broken version sets the mtu on
vpn0 to 1500.  The previous version that worked, set the mtu to 1406.
