Offload packets may be DMAed long after their SGE Tx descriptors are done
so they must remain mapped until they are freed rather than until their
descriptors are freed.  Unmap such packets through an skb destructor.

To reproduce this panic consistently, we run an intensive network
application like 'netperf'. After waiting for a couple of seconds,
you will see a stack trace and a kernel panic where we are calling
pci_unmap_single() in ql_poll().

Changes:
1)  Check the flags on the Response MAC IO Control block to check for
errors
2)  Ensure that if we are on the 4022 we only use one segment
3)  Before, we were reading the memory mapped producer index register
everytime we iterated in the loop when clearing the queue.  We should
only be iterating to a known point, not as the producer index
is being updated.

To Reproduce the Problem:
To reproduce this panic consistently, we run an intensive network
application like 'netperf' and then switch to a different console.
After waiting for a couple of seconds, you will see a tx reset has occured.

Reason:
We enable interrupts even if we were not running.

Solution:
Now we will enable interrupts only after we are ready to give up the poll
routine.

This network device driver shares the same hardware as the qla4xxx
iSCSI driver. Changing the MTU via the device interface will
cause qla4xxx to crash as there is no way to make notification.
Users wishing to change the MTU must do so using an iSCSI
utility such as Qlogic SanSurfer. This forces the user to
unload/reload this network device driver after the MTU
value has been changed in flash.

We do not need to zero out the 64 byte MAC request I/O control block.
  By zeroing out the control block and setting it to proper fields is
redundant work.  This is because in the qla3xxx_send() function we will
already set the proper fields in this structure.  The unused fields are
not looked at by the hardware and do not need to be zeroed out.

The return code was not properly set when when allocating memory or mapping
memory failed.  Depending on the stack, the return code would sometimes
return 0, which indicates everything was ok, when in fact there was an error.
  This would cause trouble when the module was removed.  Now, we will pass
back the proper return code when an error occurs during the PCI probe.

It looks like the skge driver inherited another bug from the sk98lin code.
If I send from 1000mbit port to a machine on 100mbit port, the switch should
be doing hardware flow control, but no pause frames show up in the statistics.

This is the analog of the recent sky2 fixes. The device needs to listen
for multicast pause frames and then not discard them.
