b3b1514c90 qla3xxx: bugfix: Jumbo frame handling.
Fixed rx checksum bits. Turn on TCP processing for rx checksum.
Fixed max frame length register write.  It wasn't getting set
in multi-port system. Set rx buffer queue length properly
for jumbo frames.

e8f4df2491 qla3xxx: Kernic Panic on pSeries under stress conditions
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.

3e71f6dd47 qla3xxx: bugfix: Fixed jumbo frame handling for 3032 chip.
The scatter/gather lists were not being build correctly.  When
large frames spanned several buffers the chip would panic.

1357bfcf71 qla3xxx: Dynamically size the rx buffer queue based on the MTU.
This change removes use of constants for rx buffer queue size
and instead calculates the queue length based on what he MTU
is set to.

5a4faa8737 [PATCH] qla3xxx NIC driver
This is a complementary network driver for our ISP4XXX parts.

There is a concurrent effort underway to get the iSCSI driver (qla4xxx)
integrated upstream as well.

I have been through several iterations with the linux-netdev list and have had
much response from Stephen Hemminger.

- Built and tested using kernel 2.6.17-rc4.

- The chip supports two ethernet and two iSCSI functions.

- The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and
  ql_wait_for_drvr_lock are used to protect resources that are shared across
  the network and iSCSI functions.  This protection is mostly during chip
  initialization and resets, but also include link management.

- The PHY/MII are not exported through ethtool due to the fact that the
  iSCSI function will control the common link at least 50% of the time.

This driver has been through several iterations on the netdev list and we feel
this driver is ready for inclusion in the upstream kernel.

It has been built and tested on x86 and PPC64 platforms.
