+ * 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.
+ *
