[PATCH 0/13] qla3xxx: bugfixes and cleanup after IBM/Redhat testing.

[Ron Mercer]

This patch series addresses a number of issues found when testing at IBM
and Redhat.  The patches were built and tested against the netdev/upstream
kernel on i386/x86_64/PPC64 platforms.

[PATCH 01/13] qla3xxx: Return proper error codes when the 4022/4032 is being probed

[Ron Mercer]

From: Benjamin Li <benjamin.li@qlogic.com>

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.

[PATCH 02/13] qla3xxx: Remove unnecessary memset() in qla3xxx_send()

[Ron Mercer]

From: Benjamin Li <benjamin.li@qlogic.com>

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.

[PATCH 06/13] qla3xxx: Remove API to change MTU.

[Ron Mercer]

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.

[PATCH 09/13] qla3xxx: bugfix: Fixed jumbo frame handling for 3032 chip.

[Ron Mercer]

The scatter/gather lists were not being build correctly.  When
large frames spanned several buffers the chip would panic.

[PATCH 10/13] qla3xxx: Check return code from pci_map_single() in ql_release_to_lrg_buf_free_list(), ql_populate_free_queue(), ql_alloc_large_buffers(), and ql3xxx_send()

[Ron Mercer]

From: Benjamin Li <benjamin.li@qlogic.com>

pci_map_single() could fail.  We need to properly check the return
code from pci_map_single().  If we can not properly map this address,
then we should cleanup and return the proper return code.

[PATCH 11/13] qla3xxx: bugfix tx reset after stress conditions.

[Ron Mercer]

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.

[PATCH 12/13] qla3xxx: Kernic Panic on pSeries under stress conditions

[Ron Mercer]

From: Benjamin Li <benjamin.li@qlogic.com>

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.
