Re: IEEE80154 sockets problem with kernel 4.1.15

Dear all,
i've tried to change "iface.c" file, but when i try to do a network shell command (like "ifconfig"), system stall and doesn't accept any input.
The main problem is that I'm forced to use this kernel with this OS.

Do you have any solutions to offer?

Thank you,
Luca

But when I execute this code, kernel says to me following error messages:

Do you have some tips to solve the problem?

I'm using Debian Jessie (downloaded here
http://www.variwiki.com/index.php?title=VAR-SOM-MX6_Debian_R2) with kernel
4.1.15-224528-gc28c3ac-dirty.


Some patches didn't got into stable tree, we are still some
experimental stack implementation.
We don't recommended to run such old kernel.

You maybe want to run git log $FILE on linus/master tree to see and
maybe cherry-pick patches... don't report bugs/issues if you didn't
test it on current bluetooth-next/master kernel before.
Thank you.

- Alex
