VMA ERROR when running on alias to VLAN interface #23

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. bring up VLAN interface (e.g. eth0.10) with IP (e.g. 192.168.1.100)
2. bring up alias on previously created VLAN (e.g. eth0.10:2) with IP (e.g. 
192.168.1.200)
3. run application with VMA (e.g. LD_PRELOAD=libvma.so iperf -u -c 192.168.1.1)

> What is the expected output?
