I tested the fix and validated it on different kernels versions.

All are doing fine : 6.14.11 , 6.15.11, 6.16.4

Congratulations and many thanks to Eric Dumazet for spending his time on 
repairing AX25 mkiss serial connexions.

Hamradio fans will be able to continue experimenting with AX25 using 
next Linux developments.

Keep calm, I am just saying that the bisection pointed to a fine commit,
but it took a _lot_ of time to root-cause the issue.

And the bug is in ax25, not in Paolo patch.

Please test the fix, and thank me for actually working on a fix, while
I have more urgent work on my plate.
