Ayaz Abdulla ebf34c9b6f forcedeth: fix multi irq issues
This patch fixes the issues with multiple irqs.

I am resending based on feedback. I decoupled the dma mask for
consistent memory and fixed leak with multiple irq in error path.

Thanks to Manfred for catching the spin lock problem.

Ayaz Abdulla 86a0f04387 [PATCH] forcedeth: fix initialization
This patch fixes the nic initialization. If the nic was in low power
mode, it brings it back to normal power. Also, it utilizes a new
hardware reset during the init.

I am resending based on feedback, I corrected the register size mapping
and delay after posted write.

Replace all occurences of 0xff..  in calls to function pci_set_dma_mask()
and pci_set_consistant_dma_mask() with the corresponding DMA_xBIT_MASK from
linux/dma-mapping.h.

Ayaz Abdulla fa45459e5e [PATCH] forcedeth: TSO fix for large buffers
This contains a bug fix for large buffers.  Originally, if a tx buffer to
be sent was larger then the maximum size of the tx descriptor, it would
overwrite other control bits.  In this patch, the buffer is split over
multiple descriptors.  Also, the fragments are now setup in forward order.

Manfred Spraul 1836098f97 [PATCH] forcedeth: fix random memory scribbling bug
Two critical bugs were found in forcedeth 0.47:
 - TSO doesn't work.
 - pci_map_single() for the rx buffers is called with size==0.  This bug
   is critical, it causes random memory corruptions on systems with an
   iommu.

Below is a minimal fix for both bugs, for 2.6.15.

TSO will be fixed properly in the next version.  Tested on x86-64.

Ayaz Abdulla a971c32488 [netdrvr forcedeth] support for irq mitigation
This patch contains support for different modes of interrupt mitigation
of forcedeth. It includes changes based on Jeff's comments. Currently,
the modes are changed through module parameters since ethtool does not
support something similar.

It also cleans up the handling of the three dma ring entry formats that
are supported by the driver.

Manfred Spraul 1b1b3c9b6d [PATCH] forcedeth: Initialize link settings in every nv_open()
Rdiger found a bug in nv_open that explains some of the reports
with duplex mismatches:
nv_open calls nv_update_link_speed for initializing the hardware link speed
registers. If current link setting matches the values in np->linkspeed and
np->duplex, then the function does nothing.
Usually, doing nothing is the right thing, but not in nv_open: During
nv_open, the registers must be initialized because the nic was reset.

The attached patch fixes that by setting np->linkspeed to an invalid value
before calling nv_update_link_speed from nv_open.

Manfred Spraul 22c6d143f3 [PATCH] forcedeth: Update error handling
Ayaz wrote an update to the error handling for forcedeth (which I
modified heavily, thus all bugs are mine):
The ERROR4 bit is not a fatal error, it just indicates a mismatch
between the actual packet len and the len according to the 802.3 header.
The patch adds proper handling.
The patch also removes the code that drops all packets with RX_ERROR &
(!RX_FRAMINGERR): ERROR4 errors are also not fatal.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
