Hi Larry,

Very many thanks for looking at this - I tried to look in to it
myself but realised I don't have a good understanding about what's
going on.

I won't have access to my problematic ARM system until Monday, but
I've tried this on Blackfin with musb and there's no change in
operation unfortunately.

But - I added some printk() debug in this area of the code and it
seem amsdu_to_msdu() is never called, on Blackfin or on x86 - even
when the driver is fully active and transferring data on an x86 PC.

Ian
