Hi Connor,

  Been a while since I've run HLK tests myself but IIRC there was a filter for 
the test failure, or you may need an exception. That
said, if you're happy to bump up the NDIS version and fix any compat issues 
then that would certainly be welcome. 6.4 has support
for receive segment coalescing so that would help legitimize something we've 
been doing for a long time :-)

  Cheers,
