I need to add new attribute to the network resource using extensions (i.e. network config profile) and use it in the mechanism driver (in the create_network_precommit/postcommit).<br>
If I use current implementation of Ml2Plugin, when a call is made to mechanism driver's create_network_precommit/postcommit the new attribute is not included in the 'mech_context'<br>Here is code from Ml2Plugin:<br>
<font face="courier new,monospace">class Ml2Plugin(...):<br>...<br> def create_network(self, context, network):<br> net_data = network['network']<br>...</font><div><div> <font face="courier new,monospace"> with session.begin(subtransactions=True):</font></div>
<div><font face="courier new,monospace"> self._ensure_default_security_group(context, tenant_id)</font></div><div><font face="courier new,monospace"> result = super(Ml2Plugin, self).create_network(context, network)</font></div>
<div><font face="courier new,monospace"> network_id = result['id']</font></div><div><font face="courier new,monospace">...</font></div><font face="courier new,monospace"> mech_context = driver_context.NetworkContext(self, context, result)<br>
self.mechanism_manager.create_network_precommit(mech_context)<br></font><br></div><div class="gmail_extra">Also need to include new extension in the <span style="font-family:Courier;font-size:14px">_supported_extension_aliases.</span><br>
<br>So to avoid changes in the existing code, I was going to create my own plugin (which will be very similar to Ml2Plugin) and use it as core_plugin.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Please advise the right solution implementing that.</div>

Usually you wouldn't 'inherit' one plugin in another.
