-Subject: net/tg3: Avoid delay during MMIO access
-
-From: Gavin Shan <shangw@linux.vnet.ibm.com>
-
-[ Upstream commit 6d446ec32f169c6a5d9bc90684a8082a6cbe90f6 ]
-
-When the EEH error is the result of a fenced host bridge, MMIO accesses
-can be very slow (milliseconds) to timeout and return all 1's,
-thus causing the driver various timeout loops to take way too long and
-trigger soft-lockup warnings (in addition to taking minutes to recover).
-
-It might be worthwhile to check if for any of these cases, ffffffff is
-a valid possible value, and if not, bail early since that means the HW
-is either gone or isolated. In the meantime, checking that the PCI channel
-is offline would be workaround of the problem.
