Subject: ovsdb: Make ovsdb_column_set_from_json() take table schema instead of table.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1cb29ab050c601448a89eb7311a9f07095921bbd;p=openvswitch

ovsdb: Make ovsdb_column_set_from_json() take table schema instead of table.

This function took a struct ovsdb_table but only used the 'schema' member.
An upcoming patch needs to parse a column set when only the schema is
available, so to prepare for that this patch changes
ovsdb_column_set_from_json() to only take the schema that it really needs.
