Re: [libvirt] [PATCH] nwfilter: add support for RAPR protocol

This patch adds support for the RARP protocol. This may be needed due to qemu sending out a RARP packet (at least that's what it seems to want to do even though the protocol id is wrong) when migration finishes and we'd need a rule to let the packets pass. Unfortunately my installation of ebtables does not understand -p RARP and also seems to otherwise depend on strings in /etc/ethertype translated to protocol identifiers. Therefore I need to pass -p 0x8035 for RARP. To generally get rid of the dependency of that file I switch all so far supported protocols to use their protocol identifier in the -p parameter rather than the string.
