[U-Boot] [PATCH] NetLoop initialization bug

Hi Michael,

What do you mean by this?  Usually you only need a mailer which is
capable to attach things inline.  Even better - if you have a direct
access to an mta or an smtp server, use git-send-email after
git-format-patch.

Well this is really more work for the people importing the patches, so
if at all possible, get tghe setup working with the automatically
generated patches.

Please don't elide your e-mail address here.  The consent is that we use
real e-mail addresses in the signed-off-by lines (as you also did in
your previous post).  One negative impact for example is that our
statistic scripts will fail for such entries.

Apart from that you have to nudge Ben or Heiko as to the real content.
I only wanted to help get the formalities straight ;)

Cheers
  Detlev
