Subject: be2net: Patch to determine if function is VF while running in guest
 OS.

When driver is loaded in guest OS, the pci variables is_virtfn and is_physfn are
both set to 0. This change uses registers in controller to determine the same.

Subject: be2net: fix to avoid sending get_stats request if one is already
 being processed.

GET_STATS request uses the same memory region as the response.
If a new request for get stats is fired before the response for
the previous get_stats request is received, the response will
corrupt the new request, causing the f/w to misbehave.
