Hi Alexey:

icmp4-uni-basic01 use IP_VER to check ip version. So I did this check before
ping. But as you said, I will remove the check and add TST_IPV6 in uni-basic
tests.

BTW, Would you like to help apply the patches and check the ROD issue? I
always got the following error when use ROD to run cmds.

# testscripts/networkstress.sh -i
<<<test_start>>>
