[PATCH 3.12 094/104] bnx2x: Test nvram when interface is down

From: Jiri Slaby
Date: Wed Aug 20 2014 - 07:46:01 EST


From: Yuval Mintz <yuvalmin@xxxxxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit bd8e012b5d369933f50842294372ed580f5d9605 upstream.

Since commit 3fb43eb ("bnx2x: Change to D3hot only on removal") nvram
is accessible whenever the driver is loaded - Thus it is possible to
test it during self-test even if the interface is down
