* [PATCH] sky2: more conservative transmit lockingStephen Hemminger2006-01-171-12/+31
| | | | | | | | Be more careful about transmit locking, this solves a possible race between tx_complete and transmit, that would cause a tx timeout. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* [PATCH] sky2: ratelimit error messagesStephen Hemminger2006-01-171-17/+27
| | | | | | | | Make sure and rate limit all the error messages that might occur. If a problem occurs then a few messages are enough. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
* [PATCH] sky2: optimize for 32 bit dmaStephen Hemminger2006-01-171-2/+2
| | | | | | | | Small optimization, if dma addresses are 32 bits, then high bits are always zero. Signed-off-by: Stephen Hemminger <shemminger@osdl.or> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* [PATCH] sky2: write barrier'sStephen Hemminger2006-01-171-3/+2
| | | | | | | | Be more careful about memory barriers. The only place we really need them is before and after updating the chip's ring interface. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
* [PATCH] sky2: fix ram buffer for Yukon FE rev 2Stephen Hemminger2006-01-171-22/+30
| | | | | | | | | | Fix problems with Yukon FE rev 2 chipset. Don't cut and paste bugs in from sk98lin driver. Change how the ram buffer is divided up, and make the math clearer. Also, set the thresholds where rx takes precedence. The threshold values are just guesses at this point, it might be worth tuning them later.
