Re: [libvirt] [PATCH v2] nwfilter: Enable detection of multiple IP addresses

In preparation of DHCP Snooping and the detection of multiple IP addresses per interface: The hash table that is used to collect the detected IP address of an interface can so far only handle one IP address per interface. With this patch we extend this to allow it to handle a list of IP addresses. Above changes the returned variable type of virNWFilterGetIpAddrForIfname() from char * to virNWFilterVarValuePtr; adapt all existing functions calling this function. --- v2: - fixed logic bug pointed out by Eric Blake - sorted symbols
