Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-17[PATCH] sky2: more conservative transmit lockingStephen Hemminger
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>
2006-01-17[PATCH] sky2: don't inline so muchStephen Hemminger
Don't need to inline quite so many routines, let the compiler decide Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-01-17[PATCH] sky2: ratelimit error messagesStephen Hemminger
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>
2006-01-17[PATCH] sky2: optimize for 32 bit dmaStephen Hemminger

2006-01-17[PATCH] sky2: fix ram buffer for Yukon FE rev 2Stephen Hemminger
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.
