I think you misunderstood. Look at the dev->weight.
Yep, I was definately confused. I don't see how changing the value as I did could affect anything in a good way, but I definately saw changes in dropped packets...maybe it was too late at night :) So, after further looking at the code, it appears that the dev->weight is basically hard-coded in the tulip driver, and the weight_p value in dev.c (and settable though sysctl) is not used anywhere except netdev_init (ie, not soon enough to actually set via sysctl). Think we should add an IOCTL to change the weight of a device dynamically? (I want my e1000 and tg3 to have higher weight than the tulip nics, I imagine) Is there a ready-built proc interface to do things to individual devices?
