The various Neutron plugin files need to have unique variables for the xtrace state as they are sometimes nested more than two levels deep and MY_XTRACE is getting stomped. This gives each of the neutron_plugin and neutron_thirdparty include files a unique XTRACE state variable. I don't think this is a problem with any of the other plugin include files (yet) so this just handles Neutron for now. Change-Id: I7c272a48e7974edecaff5f431ff7443dd6622588

# VMware NSX
|
|
# ----------
|
|
|
|
# This third-party addition can be used to configure connectivity between a DevStack instance
|
|
# and an NSX Gateway in dev/test environments. In order to use this correctly, the following
|
|
# env variables need to be set (e.g. in your localrc file):
|
|
#
|
|
# * enable_service vmware_nsx --> to execute this third-party addition
|
|
# * PUBLIC_BRIDGE --> bridge used for external connectivity, typically br-ex
|
|
# * NSX_GATEWAY_NETWORK_INTERFACE --> interface used to communicate with the NSX Gateway
|
|
# * NSX_GATEWAY_NETWORK_CIDR --> CIDR to configure br-ex, e.g. 172.24.4.211/24
|
