Bob Tracy <rct@gherkin.frus.com> reported that the addition of support
for Aculab E1/T1 cPCI carrier cards broke detection of vanilla natsemi
cards. This patch fixes that: the problem is that the driver-specific
ta in the PCI device table is an index into a second table and this
had not been updated for the vanilla cards.
This patch fixes the problem minimally.

Chelsio without NAPI enabled has been broken (won't compile) since
3de00b89 ("chelsio: NAPI speed improvement"):
drivers/net/chelsio/sge.c: In function `t1_interrupt`:
drivers/net/chelsio/sge.c:1716: error: `Q` undeclared (first use in this function)
The change below seems to add back in the declaration and
initialization of `Q` that was removed by mistake, and at least makes
the driver compile for me, although I have no hardware and hence no
way to test whether this actually works.

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.

If I send from 1000mbit port to a machine on 100mbit port, the switch should

This is the analog of the recent sky2 fixes. The device needs to listen
