- * Name: devif_pkt_send
- *
- * Description:
- * Called from socket logic in order to send a raw packet in response to
- * an xmit or poll request from the network interface driver.
- *
- * This is almost identical to calling devif_send() except that the data to
- * be sent is copied into dev->d_buf (vs. dev->d_appdata), since there is
- * no header on the data.
- *
- * Assumptions:
- * Called with the network locked.
- *
