Okay Thomas, got it! I'll do the required tests under *debian* and
fill a bug against Debian Linux Kernel.
But, the Kernel code related to this part of it (network and etc), is
very different in Linux 3.18, I'm guessing that it will *easier* to
just provide Jessie with Linux 3.18, instead of a patch, but, I'm
seeing that it might be
too late for that... :-(
Yes, I tested it with Ubuntu but, I also tested it using Linux from
kernel.org, compiled by myself... Only Linux 3.18 solve that issue.
Cheers!
