Hello!

Plus patch to do this is available for eepro100.

This is simply not permitted just now.
Mea culpa...
Dave, seems, it is better to repair this. Code really assumes
that SG cannot be used without one of CSUM flags...
Actually, drivers which are able to SG without checksumming
should do this. Even though just this minute this feature
has no applications. Next minute it will. Not only with decnet,
but for IP too.
