During traffic when DCB is enabled, it is possible for multiple instances
of statistics queries to be sent to the chip - this may cause the FW to assert.
This patch prevents the sending of an additional instance of statistics query
while the previous query hasn't completed.

Change various flows in the bnx2x driver which up until now flapped
the link - these flows now benefit from the link flap avoidance mechanism.
This includes the removal of the link reset made upon nic init, as it is
possible the link is already active at that time.

Various flows in the bnx2x driver cause a link-flap - if the link
is up, it would be toggled down (after a mac/phy reset) and then
taken back up.
In many of these cases, there is no need to do cause such a flap,
as the associated flows should not actually affect the link.
This patch adds the 'Link Flap Avoidance' mechanism, which allows
the driver to better determine if a given flow requires a link change,
and thus minimize the number of link flaps caused by the driver.

In order to lay the foundation for 1G EEE support, several segments of code
which are common to both 1G and 10G EEE configurations were extracted from
the 10G EEE configuration flow to their own functions.
E.g., bnx2x_eee_initial_config, bnx2x_eee_advertise, bnx2x_eee_disable, etc.
The rest of the EEE functions were relocated and placed in a single,

During probe, every function probed clears the recovery registers from
all functions on its path - thus signaling that given a future recovery
event, there will be no need to wait for those functions.
This is a flawed behaviour - each function should only be responsible
for its own bit.
Since this registers are handled during the load/unload routines,
this cleanup is removed altogether.

The 57840 boards come in two flavours: 2 x 20G and 4 x 10G.
To better differentiate between the two flavours, a separate device ID
was assigned to each.
The silicon default value is still the currently supported 57840 device ID
(0x168d), and since a user can damage the nvram (e.g., 'ethtool -E')
the driver will still support this device ID to allow the user to amend the
nvram back into a supported configuration.
