[LTP] [question] tst_rhost_run.sh not installed

[Boyang Xue]

Thanks Petr and Joerg!

Yes. I was testing with the two-host setup. Previously RHOST didn't
have LTP installed, so there's no tst_net_iface_prefix. After
installing LTP on RHOST and setting LTPROOT & PATH env variables
there, the error disappeared and it works well now.

Thanks,
Boyang
