Bugs fixed in Version 3.26


The following bugs have been fixed in SAND Version 3.26: 


Transmit Timeout Error On Busy Links Corrected

Beginning with Version 3.25 of SAND, all protocol subinterfaces were
automatically bandwidth limited based on their master interface speed. 
Under heavy traffic loads, if ports filled all of their buffers, a
"Transmit timeout" error resulted.  Version 3.26 correctly clears the
buffers on subinterfaces under heavy trafic loads.
