Subject: [PATCH 57/58] be2net: Fix EEH error reset before a flash dump
|
|
completes
|
|
|
|
commit eeb7fc7bc095546b21188e8e076a59bce73f9ca6 upstream.
|
|
|
|
An EEH error can cause the FW to trigger a flash debug dump.
|
|
Resetting the card while flash dump is in progress can cause it not to recover.
|
|
Wait for it to finish before letting EEH flow to reset the card.
