The ethtool was just a side-observation, the biggest problem was that after unbinding from igb_uio and rebinding to igb, if I follow it up with an /etc/init.d/network restart, that completely hoses the linux system - anyone trying to open a socket (ifconfig for example) just hangs. Thats how I started troubleshooting this and happened to see this ethtool thing along with it, not sure if its related. Also the issue doesn't happen with one or two interfaces, there needs to be at least five or six interfaces for this to happen. The other thing I noticed is that if I put some sleep (2 seconds) between unbind igb_uio and re-bind igb, the network-restart-hosing-system doesnt happen, but the ethtool issue still remains Rgds, Gopa.
