Hello,

I am writing ethernet network driver.
I would like to ask if there are any steps which can help when
debugging ethernet driver, or is it that the first test should already
involve transmit/recieve packets to/from ip stack ?

Any tips for debugging and testing a new ethernet driver will be appreciated,

You can start by testing the loopback mode (perhaps). Also, use wireshark
or tcpdump for capturing the packets.
