I feel, better to start from application to low level driver, as
follows:
- Try to understand/Analyze all Layers(L2,L3,L4) headers, by writing
your own packet sniffer application.
- Try to understand the basic protocols, like ARP, TCP/UDP.
- Try to understand the network packet flow(Tx/Rx), from
application/socket to network driver (hard_start_xmit()/) or vice versa.
- Try to understand any network driver (mainly, Tx/Rx packet flow)
example: intel driver e1000 (kernel-src/driver/net/e1000/*).

You'll need also to learn a lot of network theory. It's all on the RFCs
(http://www.ietf.org/rfc.html) or other good network book.
Best Regards.
