Hi All,
Thanks for your replies. Sorry for late reply. I couldnot get the hardware
to test this scenario again and i was also busy with some other things.
@Akeem: It is back to back connection, there is no switch in between. We
didnt try on the latest igb-driver.
@Jeff: Please find the output of the ethtool command executed after one
interface is made admin down.
