Comments! and/or proper symbolic names for those magic numbers would be good for a final patch, of course :) Do you believe the patch is a fix for this particular issue, or will it just reduce the probability (and hence frequency) of problems? Note that in either case the smsc911x driver is still believed to have problems of its own, like incorrect FIFO skipping on bad packets, and some SMP safety issues.
