No, you can set INPKTEND at the end of a frame to force the engine to 
commit a short packet.  Your software can detect that, when one of the 
read packets is not a multiple of 1024.  If you're driving slave FIFOs 
from an FPGA or CPLD, you can set the PKTEND signal to force the partial 
packet to be committed.
