Hi All ,
Description of problem:
I am getting error while running if4-mtu-change and if6-updown network stress interfaces test case from LTP version 20120903 (ltp-full-20120903.tar) i.e. on Linux 3.2 kernel. Below are the outputs for error.
The Network stress interfaces part of the LTP stress fails.
network_stress.interface:if4-mtu-change FAIL 2
network_stress.interface:if6-updown FAIL 2
Below are the cause for failing above mentioned testcase:
if4-mtu-change01 0 TINFO : Verify the IPv4 connectivity is not broken when ifconfig command changes MTU 128 times every 5 seconds
if4-mtu-change01 1 TFAIL : eth1 is broken.
if4-mtu-change02 0 TINFO : Verify the IPv4 connectivity is not broken when ip command changes MTU 128 times every 5 seconds
if4-mtu-change02 2 TBROK : Test Link 0 is somthing wrong.
if6-updown 1 TBROK : Link-local address is not found at eth1 on the remote host
Suggested Code changes:

This is wrong as you check the return value from the sleep command
rather than the return value form the check_icmpv4_connectivity.
