[PATCH net-next 5/5] be2net: Fix EEH error reset before a flash dump completes

[Somnath Kotur]

From: Somnath Kotur <somnath.kotur@emulex.com>

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.
