It is based on the assumption that an interface's ifindex is basically
an alias for a local MAC address, so incoming packets now are matched
to sockets based on remote MAC, session id, and ifindex of the
interface the packet came in on/the socket was bound to by connect().

For relayed packets, the socket that's used for relaying is selected
based on destination MAC, session ID and the interface index of the
interface whose name currently matches the name requested by userspace
as the relaying source interface.

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

had not been updated for the vanilla cards.

This patch fixes the problem minimally.

the driver compile for me, although I have no hardware and hence no

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.

We enable interrupts even if we were not running.

Now we will enable interrupts only after we are ready to give up the poll

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.

  By zeroing out the control block and setting it to proper fields is

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.
