Incorrect MTU on VPN connect

Bug #1498474 reported by David Burrows on 2015-09-22

Bug Description

On update to wily, vpnc vpn connects, but MTU is incorrectly set to 1500, instead of default value which is 1412. This results in connectivity issues (packet loss).

Gnomezilla bug report: https://bugzilla.gnome.org/show_bug.cgi?id=754781

I have attached the included patch from above for convenience, and tested that this indeed resolves the issue for me.

It might be worth mentioning that I had to disable the built in tests (--enable-tests=no), or pakage generation with "debuild -us -uc -b" fails on 2 of the tests relating to ipv6.

This bug was fixed in the package network-manager - 1.0.4-0ubuntu5

---------------
network-manager (1.0.4-0ubuntu5) wily; urgency=medium

  * debian/patches/git_set_vpn_mtu_9736327b.patch: set the MTU for the VPN
    interface. (LP: #1498474)
  * debian/patches/lp1446689_git_use_kernel_pppoe_6fdfb031.patch: use the
    kernel-provided pppoe interfaces rather than requiring the use of rp-pppoe
    to use PPPoE; we switched to rp-pppoe some time ago to workaround a bug in
    detecting disconnects which has seen been fixed and could be worked around
    fairly simply with the right configuration. (LP: #1446689)
  * debian/rules: don't pass --with-pppoe to configure; the option is removed
    by the above patch.
