[PATCH 3/7] conf: separate Parse/Format functions for virDomainNetTeamingInfo

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In preparation for using the same element in two places, split the
parsing/formating for that subelement out of the virDomainNetDef
functions into their own functions.
