>From the code, we can finde the defination of MAX_URI_LEN which is for eventlet.wsgi.server, we couldn't change it randomly.
"/usr/lib/python2.7/site-packages/neutronclient/v2_0/client.py"
    # 8192 Is the default max URI len for eventlet.wsgi.server 
    MAX_URI_LEN = 8192

We tried the case in both Icehouse and Juno releases, and the issue can
be happened in both releases. Please help to check and fix it. Thanks in
advance.

  From the code, we can finde the defination of MAX_URI_LEN which is for eventlet.wsgi.server, we couldn't change it randomly.
  "/usr/lib/python2.7/site-packages/neutronclient/v2_0/client.py"
      # 8192 Is the default max URI len for eventlet.wsgi.server 
      MAX_URI_LEN = 8192

  We tried the case in both Icehouse and Juno releases, and the issue
  can be happened in both releases. Please help to check and fix it.
  Thanks in advance.
