Fping package not found in 17.01.4


i want to monitor my connections: WAN, 6in4, Lan, VPN's, etc from my openWRT device with smokeping.

Smokeping Master server is on the LAN.
Integrates the remote execution of FPing via ssh/rsh into smokeping. The variable binary must point to your copy of the ssh/rsh program. The variable rbinary must point to your copy of the fping program at the remote end.

so i just need the fping binary.

So i could have an openwrt and Smokeping integration.

DISTRIB_DESCRIPTION='LEDE Reboot 17.01.4 r3560-79f57e422d'

root@openwrt:/etc# opkg update && opkg install fping
 * opkg_install_cmd: Cannot install package fping.

It was introduced to openwrt in 2005 https://github.com/openwrt/openwrt/commit/82167a2b5031937a910b7dbe7eee0fca0e6da003
it's available in trunk/master https://github.com/openwrt/packages/tree/master/net/fping
but missing in 17.01.x 15.x, ...

Any chance to have this package backported to 17.01.4? Is there a 17.01.5 planned? i guess 18.x is on the roadmap somewhere.

How can i build it for 17.01.4?

best regards
