There's still the Amiga Zorro ESP patch out in limbo - DaveM suggested
a change to enable SCSI-2 features to help with extended message bytes

up. Tuomas' fix to the driver to bypass DMA for message in works OK
though - do you want it submitted back to linux-scsi as is, or wait
for a perfect solution (pun on me ...)?
Support for more Amiga ESP cards needs to be added (got dropped in
overlapping edits between Tuomas and me, better to make a clean break
there). More testers needed at any rate.
Conclusion - I see good chances on the EtherNEC one, ditto on the
EtherNAT if we can get it tested. Need to go back and check the FAT
stuff but would suspect it is still needed - if no one but me needs
this it could keep living in my local tree though.
Just to refresh your memory, the final fix was not to bypass DMA at any
level (I did that for the command transfer, but that didn't help), but
to have a dedicated slave_configure() function in the Amiga Zorro ESP
driver that would not enable TCQ.
