[oe] [meta-networking][PATCH] tcpslice: add recipe under tcpdump

Hi Roy,
I'm not taking this one right now, I can't tell quite what the state of
it is. I wasn't able to find a place on $HOMEPAGE to download the
source (though I only spent a couple of minutes looking, since obviously
the download link is live) but the license is a bit hairy. You can't
point at ${COMMON_LICENSE_DIR} as the file to use for your checksum
since that's not part of the source. I had a quick look at a few of the
source files and it looks like a 3 Clause BSD license for everything,
but since there's not an obvious top-level LICENSE file, you probably
need to confirm that all of the source is covered by the same license
before we go anywhere with it. That it doesn't appear to have been
touched in close to a decade, source-wise, suggests to me it's either
perfectly clean or below everyone's radar (more likely the latter).
Also, can you update the recipe to use variables where appropriate -- I
guess just in SRC_URI, since it's so simple -- when you sort out the
redistribution status?
-J.
