Log Message:
Fix problem pointed out by YAMAMOTO Takashi:
In theory mbufs can have an infinite life time and could block the transmit
ring (as slots are released when the mbuf external storage is freed). To
avoid this, when we're processing the last slot of the ring copy the buffer
and release the slot immediatly.
