Re: [libvirt] [PATCHv2] Enable tuning of qemu network tap device "sndbuf" size

The sndbuf value is put inside a <tune> element of each <interface> in the domain. The intent is that further tunable settings will also be placed inside this element. <interface type='network'> ... <tune> <sndbuf>0</sndbuf> ... </tune> </interface> --- Changes from V1: sndbuf_specified is now a bool rather than an int bitfield. sndbuf is now unsigned long. Made possible by eblake's patch adding new virXPath* and virStrToLong_* functions.

+ if (virXPathULong("string(./tune/sndbuf)", ctxt, &def->tune.sndbuf) >= 0) { + def->tune.sndbuf_specified = true; + }
