Key changes are:
- EQ ids are not assigned consecutively in Lancer. So, fix mapping of MSIx
  vector to EQ-id.
- BAR mapping and some req locations different for Lancer.
- TCP,UDP,IP checksum fields must be compulsorily set in TX wrb for TSO in
  Lancer.
- CEV_IST reg not present in Lancer; so, peek into event queue to check for
  new entries
- cq_create and mcc_create cmd interface is different for Lancer; handle
  accordingly

Since interrupts are enabled only when open is called on the interface,
Attempting a firmware update operation when interface is down could lead to
partial success or failure of operation. This fix fails the request if
netif_running is false.

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().

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.

The ONLINE registers can return 0xFFFFFFFF on more than one
occassion. On systems that care, reading these registers could

fresh skbs have ip_summed set to CHECKSUM_NONE (0)

We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.

Introduce skb_checksum_none_assert() helper so that we keep this

skb->ip_summed = CHECKSUM_NONE;

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.
