Subject: xenserver: Whitelist specific XAPI fields to pickle in interface-reconfigure.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=171ed168592f59b95fa0a3ef3a5ad60262881811;p=openvswitch

xenserver: Whitelist specific XAPI fields to pickle in interface-reconfigure.

Only add certain fields to the database cache of database
objects. This constrains the cases we need to deal with when
pickling/unpickling.

CP-1148.
