Jamal take it easy with the subject lines :-)

The subject line should be as concise, and be formatted as:

[net-next PATCH N/M] ${SUBSYSTEM}: Description.

And "Description." needs to be shorter and more reasonable that what
you supplied here.  Much of that text belongs in the commit message
body instead.

Same goes for patch #2 of this series.

LOL.Cant think of anything clever to say to that.
Maybe you should just accept my attachments ;->

Anyways, I have to resend the patches to consider
the comments from Vlad.

cheers,
