Here are two pactches that I am using currently. I sent it here if that can
help someone.
With them, is gone away something wich caused REJ packets and a lot of
retransmissions.
But behind there is maybe a problem with the REJ procedure, wich still
sometimes produce usefullness retransmission. So the real solution will be
maybe to "cure" that.
1) Forget the patch I sent last week for ax25_timer.c.
2) Go to /usr/src/linux/net/ax25
3) Do backups of originals ax25_in.c and ax25_out.c
4) Apply this patches, with "patch < file_name_of_the_patch"

5) Tell me if you notice that goes better !
6) Here in tcp/ip mode using connected mode, I see a good improvement.
