[Linux-decnet-user] Some fixes backported to 2.4
|
From: Steven W. <st...@gw...> - 2003-04-17 22:30:10
|
Hi,
Here is a patch with some of the fixes from the 2.5 DECnet stack, but none
of the new features. There are other things which need fixing too, but this
will deal with several issues and is relatively straight forward so I'm
hoping to submit this sooner rather than later and follow up with further
patches as time permits,
Steve.
