[LTP] [PATCH v1] ns-tools: Restore ns-icmpv4_sender

[Petr Vorel]

Hi Wei,

> Commit 19c9b694c6b ("ns-tools: Remove unused tools") removed
> ns-icmpv4_sender.c, assuming it was unused. However, it is still
> required by broken_ip tests (e.g. broken_ip4-version, broken_ip4-ihl),
> which were not removed.

> Restore ns-icmpv4_sender.c and update Makefile, .gitignore and
> 00_Descriptions.txt accordingly.

Good catch, thanks! Merged.

Kind regards,
Petr
