Could you check if this frame is a retry ? I would need the
frame in the same direction just before.

This are ling turnaround. It look like the S25 forget to
turnaround the link (spec violation), or packets got lost.

Same deal. Weird.

The S25 decides to close the connection.
The IrDA side of things look more or less proper on Linux
side. It looks like the higher layer on Linux side stop sending
data. I guess that's the reason why the S25 decides to close the
connection.
Really weird.

One possible explanation is that the link from Linux -> S25 is
bad and too many frames got lost. But I would need to check retries to
confirm.
