No it does not ask for a password. if I execute command on my target shell :- ssh -n -q root@xxx.xxx.xxx.xxx 'sh -c    '\' ip link set eth0 down  || echo RTERR'\''' , It runs successfully and doesn't stuck and not asking for password, i have made password authentication "no" . But when same command execute within testcase it stuck there.

Another thing is test_net.sh does not use LTP_RSH as you told. It is using below command :
 if [ -n "$TST_USE_SSH" ]; then
        output=`ssh -n -q $user@$RHOST "sh -c \
            '$BIN_PATH$pre_cmd $cmd $post_cmd'" $out 2>&1 || echo 'RTERR'`
So the env variable LTP_RSH exported by me does not have any role here. test_net.sh simply use ssh to connect  remote machine which it is able to connect but command doesn't return  anything and stuck at this moment.

If you see it is actually doing "ip link set eth0 down  " for the remote host. And I can see the eth0 becomes down on remote machine. But command  stuck after making eth0 down.

Thanks

LTP_RSH is not used in test_net.sh/tst_rhost_run(), which is sourced by 
broken_ip test group.
So it will be as you wrote below without your private key.

You could try to create alias ssh='ssh -o StrictHostKeyChecking=no -i 
/root/.ssh/id_rsa'
and then run the test.
