I am observing an transmit hang of the igb driver when the cable is =
unplugged. It only recovers after unit reset, such as
ifconfig igb0 down up
This is with kernel

Has anyone experience something like this? Is there solution? It is very =
inconvenient to have to down/up the interfaces manually via the IPMI =
console when such thing happens.
