The PF was not correctly registering any of its VLANs.  As a result any
VLAN tagged traffic from the VF would not be delivered to the PF because
the VLAN was never assigned to the PF pool.

In addition the VF was not allowed to receive traffic from VLAN 0 if it was
allowed to receive untagged frames.  This change corrects that so that it
will correctly receive traffic from VLAN 0.

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.

QMI requests exceeding 1500 bytes are possible and
device firmware does not handle fragmented messages
very well.  It is therefore necessary to increase
the maximum message size from the current 512 bytes.

The protocol message size limit is not documented
in any publicly known source, but the out of tree
driver from CodeAurora use 4 kB.  This is therefore
chosen as the new arbitrary default until the real
limit is known.

This should allow any QMI message to be transmitted

Currently, all the time limits in the bonding ARP monitor are in
multiples of arp_interval -- the time interval at which the ARP
monitor is periodically scheduled.

With a fast network round-trip and a little scheduling latency
of the ARP monitor work, a limit of n*delta_in_ticks may
effectively mean (n-1)*delta_in_ticks.

This is fatal in case of n==1  (the link will stay down
forever) and makes the behaviour non-deterministic in all the
other cases.

Add a delta_in_ticks/2 time slack to all the time limits.

it is accessing plat variable via freed memory priv pointer which gets
freed by free_netdev called from stmmac_dvr_remove.

In short this patch caches the plat pointer in local variable before
calling stmmac_dvr_remove to prevent code accessing freed memory.

This patch adds a basic check in stmmac_mdio_unregister to see if mdio
bus registeration for this driver was actually sucessfull or not.

Use case here is, if BSP considers using mdio-gpio bus along with stmmac
driver by passing mdio_bus_data as NULL in platform data.
Call to stmmac_mdio_register with mdio_bus_data as NULL returns 0, which
is a considered sucessfull call form stmmac. Then again when we unload
the driver we just call stmmac_mdio_unregister, this is were the actual
problem is stmmac-mdio code dont really know at this instance of calling
that stmmac_mdio_register was actually successful.

So Adding a check in stmmac_mdio_unregister is always safe.

Without this patch stmmac driver calls stmmac_mdio_register from
stmmac_release which Segfaults as mii bus was never registered at the
first point.

Originally the this bug was found when unloading an stmmac driver
instance which uses mdio-gpio for smi access.

so that we have on centralized area to review what buffer sizes will be
