Networking configuration options in Configuration Reference

[Ashish Billore]

Reference to depricated option "segment_mtu" in Networking configuration options in Configuration Reference

In link: http://docs.openstack.org/mitaka/config-reference/networking/networking_options_reference.html#agent

For option: network_device_mtu = None
It is suggested: (Integer) DEPRECATED: MTU setting for device. This option will be removed in Newton. Please use the system-wide segment_mtu setting which the agents will take into account when wiring VIFs.

As per this link: http://docs.openstack.org/mitaka/config-reference/tables/conf-changes/neutron.html
"segment_mtu" itself is depricated in Mitaka and instead "global_physnet_mtu" should be used.

So, above description for "network_device_mtu" should be corrected to:

(Integer) DEPRECATED: MTU setting for device. This option will be removed in Newton. Please use the system-wide global_physnet_mtu setting which the agents will take into account when wiring VIFs.

Thank you for you reporting.
The config reference is auto-generated one (based on source code help message).
You should first change following help message first.

Thanks Atsushi for the pointers, I'll correct it in the above mentioned file/line.

    Refer to correct global_physnet_mtu option instead of segment_mtu

    The help message for network_device_mtu was referring to deprecated
    option name.

    This patch is Mitaka only because in Newton the help text was completely
    removed with the network_device_mtu option.
