Once the data has been successfully sent by the interface (or if an
error occurs), the driver should call 'eth_drv_tx_done()' using the
specified 'key'.  Only then will the upper layers release the resources
for that packet and start another transmission.

"Resources" in that case are mbufs, so if you don't call tx_done (or use
the wrong key when calling it), you'll leak mbufs.
