sky2: truncate oversize packets

2006-03-09T22:19:03+00:00

Turn on truncation to prevent getting choked by frames larger than expected.
Without this fix, driver hangs after receiving an oversize packet.

sky2: force early transmit interrupts

2006-03-09T22:19:02+00:00

Avoid premature transmit ring full conditions.
Force a transmit status interrupt if transmit ring gets nearly full
and after a TSO send.

Allow more entries in transmit ring to be used if dma_addr is 32 bits

sky2: not random enough

2006-03-09T22:19:01+00:00

Don't use sky2 to seed random pool beacause the network packet arrival time
will not be truly random due to NAPI and interrupt mitigation.

[PATCH] sky2: remove MSI support

2006-02-28T23:06:25+00:00

Remove Message Signaled Interrupt support (for 2.6.16).
MSI is inherently edge-triggered and that is incompatiable (without more
work) with NAPI.

In future, will replace with smarter lockless-IRQ handling like
tg3.c

[PATCH] sky2: close race on IRQ mask update.

2006-02-23T00:25:26+00:00

Need to avoid race in updating IRQ mask.  This can probably be replaced
smarter use of the interrupt control registers (if/when chipset
docs are available).

[PATCH] sky2: use device iomem to access PCI config

2006-02-23T00:25:23+00:00

To avoid problems with PCI config access without ACPI (or busted ACPI tables),
use the device's window into PCI config space.

I know this probably will upset the purists, but I would rather have users
than ACPI testers. It also generates less code.

[PATCH] sky2: force early transmit status

2006-02-23T00:25:03+00:00

Need to force a transmit coalesce timer restart after processing
transmit packets. Otherwise, can get transmit status after last
update and chip doesn't send the next one.

Can go with the chip defaults for coalescing timers, except for
Tx timer which needs to be bigger.

[PATCH] sky2: poke coalescing timer to fix hang

2006-02-23T00:24:04+00:00

Need to restart the interrupt coalescing timer after clearing the interrupt,
to avoid races with interrupt timer and processing.

[PATCH] sky2: limit coalescing values to ring size

2006-02-23T00:23:40+00:00

Don't allow coalescing values to be bigger than the transmit ring.
Since if you set them that big, the interrupt never happens and driver
livelocks.

[PATCH] sky2: yukon-ec-u chipset initialization

2006-02-23T00:23:36+00:00

Add more complete setup code for Yukon EC_U chipset.
Based on matching code in 8.31 code in SysKonnect vendor driver.
