[patch 05/46] bnx2x: Removing the PMF indication when unloading

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Eilon Greenstein <eilong@xxxxxxxxxxxx>

commit 9a0354405feb0f8bd460349a93db05e4cca8d166 upstream.

When the PMF flag is set, the driver can access the HW freely. When the
driver is unloaded, it should not access the HW. The problem caused fatal
errors when "ethtool -i" was called after the calling instance was unloaded
and another instance was already loaded
