2005-12-12[PATCH] sky2: tx/rx ring data structure splitStephen Hemminger

2005-09-28[PATCH] sky2: cleanup interrupt processingshemminger@osdl.org

2005-09-28[PATCH] sky2: changing mtu doesn't have to reset linkshemminger@osdl.org
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. Signed-off-by: Stephen Hemminger <shmminger @osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-09-21[PATCH] sky2: version 0.5Stephen Hemminger

2005-09-21[PATCH] sky2: allow ethtool debug access to all of PCI spaceStephen Hemminger
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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-09-21[PATCH] sky2: fix FIFO DMA alignment problemsStephen Hemminger
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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-09-16[PATCH] sky2: driver update.Stephen Hemminger
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. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-17[PATCH] sky2: new experimental Marvell Yukon2 driverStephen Hemminger
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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
