After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only replace F/W specific error codes with Linux kernel generic, all EIO errors suddenly started to be converted into EAGAIN which leads nvmupdate to retry until it timeouts and sometimes fails after more than 20 minutes in the middle of NVM update, so NVM becomes corrupted. The bug affects users only at the time when they try to update NVM, and only F/W versions that generate errors while nvmupdate. For example, X710DA2 with 0x8000ECB7 F/W is affected, but there are probably more... Command for reproduction is just NVM update: ./nvmupdate64 In the log instead of: i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM) appears: i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM i40e: eeprom check failed (-5), Tx/Rx traffic disabled The problematic code did silently convert EIO into EAGAIN which forced nvmupdate to ignore EAGAIN error and retry the same operation until timeout. That's why NVM update takes 20+ minutes to finish with the fail in the end.
