Re: [PATCH] network: allow "modify" option for DNS-Srv records

The "modify" command allows to replace an existing Srv record (some of its elements respectively: port, priority and weight). The primary key used to choose the modify record is the remaining parameters, only one of them is required. Not using some of these parameters may cause duplicate records and error message. This logic is there because of the previous implementation (Add and Delete options) in the function. Tests in networkxml2xmlupdatetest.c contain replacements of an existing DNS-Srv record and failure due to non-existing record.
