Testing flent with IPv6 Addresses yields a similar error to Issue #214, despite installing the irtt tool. (IPv4 works fine with irtt, already tested.)

Running in -v to verbose showed me, that the format of IPv6 addresses is false for irtt:
Part of the output:
which: Found irtt executable at /usr/bin/irtt
UDP RTT test: Cannot use irtt runner (Irtt connection check failed: Error: address fe80::200:aff:fe00:601%h1-eth0:0: too many colons in address
). Using netperf UDP_RR
Ping (ms) UDP EF: Adding child NetperfDemoRunner

flent is run with --local-bind and -H in my case, for address handover of client and server.

Scrolling a bit through the irtt docs, I found that the host format for IPv6 addresses should be in brackets [ ]

Handing over the --local-bind in bracket format as a quick test solves the irtt issue with that address, but of course results in the address resolution to fail

Any help or quick fix is much appreciated!
