I do not know if it is an SW problem. 1. Does the problem reproduce on the latest upstream kernel?(worth to check) 2. I do not see this crash in our labs. I haven't a platform with six i226 parts.(Trying find folks who work with this platform.) 3. I am working on a patch to address .ndo_tx_timeout support. (pass the reset task to netdev while the link disconnected during traffic, under testing). It could be related and worth checking - please, let me know if you want to apply on your platform (against upstream).
