Sorry, but I think this bug should be fixed with kdump-tools?

Title:
  pVM:pinelp2:ubuntu 16.04: Network is unreachable when using ssh in
  kdump

Status in makedumpfile package in Ubuntu:
  Fix Released
Status in makedumpfile source package in Xenial:
  Fix Committed

Bug description:
  [SRU justification]
  Without this fix, networked enabled kernel dump will fail to complete.

  [Impact]
  Broken networked functionality

  [Fix]
  Add a Wants target to the systemd unit.

  [Test Case]
  Follow "Test to reproduce" in Original Problem description.

  [Regression]
  None expected, the existing systemd unit setup remains but is improved by 
proposed fix.

  [Description of the problem]

  Original problem Description
  ============================
  When dumping to ssh target , kdump failed:

           Starting Kernel crash dump capture service...
  [   18.542292] kdump-tools[2748]: Starting kdump-tools: ssh: connect to host 
10.33.31.113 port 22: Network is unreachable
  [   18.542894] kdump-tools[2748]:  * kdump-tools: Unable to reach remote 
server root@10.33.31.113. No reason to continue
  [   18.613376] kdump-tools[2748]: Mon, 11 Apr 2016 01:23:55 -0500
  [   19.310893] kdump-tools[2748]: Rebooting.
  [   19.652714] reboot: Restarting system

  But the weired thing is that nfs target works on the same system.

  ---uname output---
  Linux pinelp2 4.4.0-18-generic #34-Ubuntu SMP Wed Apr 6 14:00:30 UTC 2016

  Steps to Reproduce
  ===================================
  1. install latest ubuntu 16.04 on pinelp2
  2. config kdump to use ssh:
  SSH="root@10.33.31.113"
  3. run "kdump-config propagate" as root
  4. trigger kdump

  Userspace tool common name: kdump-tools

  The userspace tool has the following bit modes: 64-bit

  Userspace rpm: version 1:1.5.9-5

  I saw the same problem when dumping to medlp4 with ssh:

           Starting Kernel crash dump capture service...
  [   17.293028] kdump-tools[2733]: Starting kdump-tools: ssh: connect to host 
10.33.7.181 port 22: Network is unreachable
  [   17.293692] kdump-tools[2733]:  * kdump-tools: Unable to reach remote 
server root@10.33.7.181. No reason to continue
  [   17.405333] kdump-tools[2733]: Sun, 17 Apr 2016 20:56:59 -0500
  [   18.536587] kdump-tools[2733]: Rebooting.
  [   18.903280] reboot: Restarting system

  but I can ssh log noto medlp4 before triggering kdump.
