[Buildroot] [PATCH/RFC] add tcpreplay tool

[Chris Packham]

Hi Buildroot,

Is there any interest in incorporating tcpreplay as a package?

The tcpreplay tool can be used to generate packets out a specified interface
based on a pcap file from tcpdump or wireshark or anyother tool that generates
a "standard" pcap file.

The tcpreplay suite also ships with other tools (tcprewrite, tcpreplay-edit)
for manipulating pcap files.

Sorry for the spam but I think gmail ate my homework. If there is
interest I can resend the patch as an attachment.

Yes, there's always interest in adding more useful packages to buildroot.

It should be possible to shorten the makefile significantly by using
the package/Makefile.autotools.in infrastructure to e.g. do the
download, patch, autoconf and configure steps. See for example
package/midori/midori.mk.

Now buildroot is maintained in git it is preferable to submit patches
as git patches with a Signed-off-by line, and patches that are
submitted in that way are usually applied more quickly. It's also a
good idea to open a new feature request in the bugzilla so your patch
does not get lost.
