Re: [libvirt] [PATCH] nwfilter: Some fixes to XML parser

While writing a couple of test cases for the nwfilter's XML parser I found some cases where the output ended up not looking as expected. So the following changes are in the patch below: - if the protocol ID in the MAC header is an integer, just write it into the datastructure without trying to find a corresponding string for it and if none is found failing - when writing the protocol ID as string, simply write it as integer if no corresponding string can be found - same changes for arpOpcode parsing and printing - same changes for protocol ID in an IP packet - DSCP value needs to be written into the data structure - IP protocol version number is redundant at this level, so remove it - parse the protocol ID found inside an IP packet not only as string but also as uint8 - arrange the display of the src and destination masks to be shown after the src and destination ip address respectively in the XML - the existing libvirt IP address parser accepts for example '25' as an IP address. I want this to be parsed as a CIDR type netmask. So try to parse it as an integer first (CIDR netmask) and if that doesn't work as a dotted IP address style netmask. - instantiation of rules with MAC masks didn't work because they weren't printed into a buffer, yet.
