When async mcc compls are rcvd on an i/f that is down (and so interrupts are disabled)
they just lie unprocessed in the compl queue.The compl queue can eventually get filled
up and cause the BE to lock up.The fix is to use be_worker to reap mcc compls when the
i/f is down.be_worker is now launched in be_probe() and canceled in be_remove().

Calling netif_carrier_off before register_netdev was causing the network interface
to miss a linkwatch pending event leading to an inconsistent state if the link
is not up when interface is initialized.This is now invoked after register_netdev.

Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb. There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances. However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

occassion. On systems that care, reading these registers could

The BE ASIC/firmware doesnot reserve and assign MAC address for VFs.
This results in the VF interfaces being created with MAC Address 0.
The code change proposed takes the MAC address of PF to generate a seed.
MAC Address for VFs are assigned incrementally starting from the seed.
These addresses are programmed in the ASIC by the PF and the VF driver
queries for the MAC address during its probe.
