Last time I had a chance to try this on a non-broken EtherNAT, it was 
fine (two years ago IIRC). Need to ask Christian again to test the 
current one. There was one change you suggested after that time 
(dropping a dodgy cast was part of it) - that bit got never tested. It 
should work from what we discussed, but that's not a strong enough 
argument.

I'll leave it up to you to decide whether this is fit to submit.

That one's fine. Paul had objections to the way I handled the shared 
interrupt and polling issue but that has been resolved a while ago.

Time for me to resubmit that one.

Agreed - it works but  there has to be a cleaner way to do this. I need 
to sit down and understand how it is that the current code works. (Last 
time I tried, the USB chip still worked on my EtherNAT so I can keep 
handling this.)

I have a hard time remembering what these were about. Setting the 
'atari' option to either no or yes makes no difference, the mount works 
either way on my GEMDOS partition. The other two I suspect are needed 
(can be merged into one, anyway). I'll try to drop them and see where 
that leaves me.

I don't think I still have the test disk image I got from Petr to test 
these patches on. The patches were needed in 2009 so probably are still 
needed now. What were the objections from the FAT maintainers here?

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 but 
that did not work as intended. Haven't had time to follow that one 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.

Leaves USB to clean up, and SCSI stuff (which is what I have mostly been 
working on (Atari), if any).

Not much help, I know. I need a clone or two.

Cheers,

    Michael
