Title:
  VPN connections with juniper network connect have zero throughput

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Starting with linux 3.19 the juniper network connect client
  establishes the VPN connection but has zero throughput on the virtual
  network adapter.

  The log of the VPN client software show the following message:
  adapter.warn IP Packet too small 0

  The problem is known and fixed in 3.19.2 IIRC. The relevant patch is mentioned here:
  https://bugzilla.kernel.org/show_bug.cgi?id=90901
  in comment 2.

  The fix is not part of 3.19.0-14-generic.

  A backport of the patch would be great, a downgrade to linux 3.16 is a viable workaround for the time being.
