[PATCH] Wrong return value corrupts free object in e1000 driver
For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT
instead of one of the NETDEV_TX_* error codes. In fact, it frees up
the SKB before returning this. This makes the queueing layer think
the packet should be requeued and subsequently we corrupt a freed
object.
