Hello Am new to using Genode. As part of my project work i would like to better understand the working of the Ethernet stack in Genode. Your help will be highly appreciated.

Hello Ssekyanzi,
welcome to the list! Can you share the motivation behind your question? I.e., what kind of networking scenario do you have in mind?

To gain a good understanding of networking on Genode, I recommend you to experiment with the run scripts found in the libports and ports repositories. I would start with repos/libports/run/lwip.run, which runs a simple web server using the lwIP TCP/IP stack. The network driver is executed as a separate component.
For sharing one physical NIC between multiple components, there is the so-called NIC bridge, located at os/src/server/nic_bridge/. It opens a session to a NIC driver and, in turn, provides potentially many NIC sessions to its clients. Each client gets an IP address at the host network.
There are two TCP/IP stacks available, the lwIP stack and the TCP/IP stack ported from the Linux kernel (located in the dde_linux repository). Each of both comes in the form of a library that is linked directly against the network application.
For all of the components mentioned above, you can find run scripts as examples. If you have questions about a specific component or run script, please do not hesitate to ask.
Best regards Norman
