sure, no problem. 

You'll find the core network components here:
src/VBox/Devices/Network/SrvIntNetR0.cpp  (the switch/hub)
src/VBox/HostDrivers/VBoxNetFlt/ (the network code interfacing the kernel)

Standalone programs using the network components:
src/VBox/Devices/Network/testcase/tstIntNet-1.cpp (check out the -S option)
src/VBox/NetworkServices/DHCP/VBoxNetDHCP.cpp (another example)
