Added support for VDE (Virtual Distributed Ethernet) network packet transport

Browse Source 
Fixed filtering for non-pcap network packet transports (i.e. tun/tap, and vde) to properly filter the desired packets.

-------------------------------------------------------------------------------
An alternative to direct pcap and tun/tap networking on *nix environments is
VDE (Virtual Distributed Ethernet).
Note 1: Using vde based networking is likely more flexible, but it isn't
nearly as efficient. Host OS overhead will always be higher when
vde networking is used as compared to native pcap and/or tun/tap
networking.
Note 2: Root access will likely be needed to configure or start the vde
environment prior to starting a simulator which may use it.
Note 3: Simulators running using VDE networking can run without root
privilege.
Linux (Ubuntu 10.04):
apt-get install libvdeplug-dev
apt-get install vde2
vde_switch -s /tmp/switch1 -tap tap0 -m 666
ifconfig tap0 192.168.6.1 netmask 255.255.255.0 up
