shemminger@osdl.org d11c13e752 [PATCH] sky2: cleanup interrupt processing
The receive processing can be cleaned up by not using local variables
to store checksum status, instead just put it directly onto the expected
skb.

shemminger@osdl.org 6b1a3aefd8 [PATCH] sky2: changing mtu doesn't have to reset link
Changing the MTU of the network device doesn't mean the whole link
has to be brought down and back up again.  Just stopping the receive
engine is good enough.

Stephen Hemminger 6e4cbb34d4 [PATCH] sky2: allow ethtool debug access to all of PCI space
For debugging, it is useful to allow ethtool to dump all of
the PCI mapped space. There is one small set of registers for RAM
diagnostics that needs to be avoided to prevent hanging, but all
the rest is accessible.

Stephen Hemminger 79e57d32fe [PATCH] sky2: fix FIFO DMA alignment problems
The Yukon2 chip FIFO has a problem recovering from a pause frame
if the receive buffer is not aligned. The workaround is to just
leave receive buffer at original alignment, which will make IP
header unaligned. Rework receive logic for clarity.

Need to ignore receive overrun interrupts (or mac hangs).

These fixes make the sky2 driver generally usable.

Stephen Hemminger 793b883ed1 [PATCH] sky2: driver update.
Here is revised patch against netdev sky2 branch.
It includes whitespace fixes, all the changes from the previous
review as well as some optimizations and timing fixes to
solve some of the hangs.

The stall problem is better but not perfect. It appears that
under stress the chip can't keep up with the bus
and sends a pause frame, then hangs. This version is for
testing, and hopefully other eyes might see the root
cause of the problem.

I don't want to reinvent the ugly watchdog code in the syskonnect
version of sk98lin.  If you read it you will see, the original
driver writer and the hardware developer obviously didn't
understand each other.

Dual port support is included, but not tested yet. It did
require small change to NAPI since both ports share same
IRQ.

Stephen Hemminger cd28ab6a4e [PATCH] sky2: new experimental Marvell Yukon2 driver
New driver for the Marvell Yukon2 Gigabit Ethernet chipset.
This driver is based on the skge driver, but using the logic
from the SysKonnect version of the sk98lin driver.
It should support all the Yukon2 chipsets that are available
in many current Intel and AMD motherboards.

The driver does support ethtool, tx and rx checksum, and
tcp segmentation offload.  But it has only been tested for
a short while and is known to stop receiving under heavy load.
