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

From: Yuval Mintz <yuvalmin@...adcom.com>

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
