comment How virbr0-nic is created?
The poster of the question seems to understand what the bridge does and what the dummy device does, he just wanted to know how to create similar interfaces. You are welcome to improve the answer if you feel it could be better.

comment NAPI vs Adaptive Interrupts
@Alex Hardware interrupts must be used to notify the kernel there is traffic to receive. An "old style" interrupt handler schedules packet receive then re-enables interrupts. A NAPI interrupt handler disables interrupts, schedules a poller, and re-enables interrupts. The poller performs packet receive for a certain amount of packets, and as long as there is traffic to service the poller keeps running, the aim being to prevent hard interrupts by always drawing traffic off the NIC. When traffic dies down, the poller exits and the system goes back to waiting for an interrupt.

comment Circular directory structure
What's the exact message you get? Is it the directory <name> contains a readdir loop? This can happen because the NFS Server returns the same READDIR cookie for two different files in the same directory. If so, this would be a bug in the NFS Server.

comment Circular directory structure
The inode number does not matter, at least on Linux. It is expected that different NFS exports could have files which share the same inode number. This is possible because an export is a filesystem, and inodes are only unique to the filesystem. Both Linux NFS Server and Client can handle files in different NFS exports with the same inode number (at least in RHEL6 and 7).

comment Tcpdump/Iptables on bridge interface without assigned IP address
I don't know if this is helpful, but a bridge interface will only see traffic one way in a packet capture. You would be better to perform a packet capture on the bridge port interfaces, i.e tap0 and tap1

comment arp problems with transparent bridge on linux
I understand, though I still think you've got a network loop elsewhere in the network and ARP is being broadcast back to you. Maybe that's a behaviour of VMWare or a setting within the VMWare VSwitch?
