Hi Petr,

Some very old stress tests use check_envval(instead of tst_net.sh) to
init LTP_RSH,
Do you think if we need to change it as well:
--------------------------------------
# LTP_RSH
LTP_RSH=${LTP_RSH:=}
if [ x"${LTP_RSH}" = x ]; then
LTP_RSH="rsh -n"
elif [ "$LTP_RSH" = "rsh" ]; then
LTP_RSH="rsh -n"
fi
--------------------------------------

Thanks,
Xiao Yang
