I'm performing a set of tests on an embedded device, one of which is "To verify that the control system and instrument supports auto-negotiation". I need to verify that "Expected auto-negotiation is achieved based on ability flags".
From what I understand the auto-negation messages and the ability flags don't go beyond the NIC, so I wont be able to capture them using wireshark.
Is this assumption correct, and if so, how can I inspect these messages?
