There is a patch to add a debugging /proc/net/sky2/ethX interface to dump
status rings. This interface will not be part of released drivers and should
not be shipped in distribution kernels. It doesn't handle things like
device renaming and is purely released as is.

You can use this to see if status or tx ring are hanging.
