Hi,
This is a patch to incorporate comments from earlier 12 patches.
It also fixes a few issues we found during this time.
Following is a list of changes in this patch. Item 1 incorporates
earlier comments. Issues addressed in items 2 to 4 were discovered
recently.
1. wmb() call in s2io_xmit() replaced with mmiowb().
2. The dtx_control register was earlier programmed incorrectly
for Xframe II adapter.
3. As suggested by hardware team, after a reset, in case of
Xframe II adapter, we clear certain spurious errors by
clearing PCI-X ECC status register, "detected parity error"
bit in PCI_STATUS register and PCI_STATUS bit in txpic_int register.
4. On IBM PPC platforms, we found that in the Rx buffer replenish
function, two memory writes(one to the the descriptor length and
another to the ownership) were getting reordered. This was causing
the adapter to see the ownership transfered to it before the length
was updated.
One solution was to add a wmb() but since this would turnout expensive
on some platforms if called for every descriptor, we set the ownership
bit and other fields of '2' to 'N' Rx descriptors followed by a wmb()
and then set the ownership of first descriptor ('1').
Here the value 'N' is configurable by making it a module loadable
parameter (rxsync_frequency).
(NOTE: This parameter is a power of 2).
5. Bumped up the driver version no. to 2.0.2.1

Hi,
The last patch in this series fixes the following issues found during
testing.
1. Ensure we don't pass zero sized buffers to the card(which can lockup)
2. Restore the PCI-X parameters(in case of Xframe I adapter) after a reset.
3. Make sure total size of all FIFOs does not exceed 8192.

Hi,
This is a patch to provide bimodal interrupt moderation support for
Xframe II adapter. Basically, in this moderation scheme, the adapter
raises a traffic interrupt if the no. of packets transmitted and/or
received reaches a programmable threshold.

Hi,
This patch provides basic support for the Xframe II adapter.
Includes the following changes:
1. New values to program XAUI interface.
2. Print the PCI/PCI-X mode(bus frequency, width).
3. Remove EOI from reset during intialization.
4. Enable all 8 PCCs if Xframe II adapter.
5. Programs the RLDRAM size depending on the device.
(Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb).
6. Enable extended(64-bit) statistics counters.
7. Program timer interrupt duration based on PCI/PCI-X clock speed.
8. Not required to save/restore PCI config space before/after reset.

Hi,
This patch relates to mostly performance related changes.
1. Fixed incorrect computation of PANIC level in rx_buffer_level().
2. Removed unnecessary PIOs(read/write of tx_traffic_int and
rx_traffic_int) from interrupt handler and removed read of
general_int_status register from xmit routine.
3. Enable two-buffer mode(for Rx path) automatically for SGI
systems. This improves Rx performance dramatically on
SGI systems.

Hi,
Below patch includes fixes for few purely software bugs identified
since last release.
1. Keep track and display(as part of ethtool command output) the no.
of single-bit and double-bit ECC errors.
2. Handle race condition between intr handler and "interface down"
routine.
3. Initial link state setting modified so that the link state displayed
after "interface Up" is correct.
4. Fix for "Incorrect Tx packet count when TSO is enabled".
5. Disable periodic DMA of statistics and schedule one-shot DMA
only when required.

Hi,
Below patch addresses few h/w specific issues.
1. Check for additional ownership bit on Rx path before
starting Rx processing.
2. Enable only 4 PCCs(Per Context Controller) for Xframe I
revisions less than 4.
3. Program Rx and Tx round robin registers depending on
no. of rings/FIFOs.
4. Tx continous interrupts is now a loadable parameter.
5. Reset the card if we get double-bit ECC errors.
6. A soft reset of XGXS being done to force a link state change has been
eliminated.
7. After a reset, clear "parity error detected" bit,
PCI-X ECC status register, and PCI_STATUS bit in
tx_pic_int register.
8. The error in the disabling allmulticast implementation has been
rectified.
9. Leave the PCI-X parameters MMRBC, OST etc. at their
BIOS/system defaults.

This patch makes tms380tr use the new DMA API. Now that on Alpha, this API
also supports bus master DMA for ISA (platform) devices, i changed the
driver to use this new API.
This also works around a bug in the firmware loader: The example provided
in Documentation/firmware_class no longer works, as the firmware loader now
calls get_kobj_path_length() and the kernel promptly oopses, as the
home-grown device doesn't have a parent. Of course, this doesn't happen
with a "real" device which has its bus (or pseudo bus in the case of
platform) as parent.
Converted tms380tr to use new DMA API:
- proteon.c, skisa.c: use platform pseudo bus to create a struct device
- Space.c: delete init hooks
- abyss.c, tmspci.c: pass struct device to tms380tr.c
- tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader
