| The syncppp drivers in Linux provide a fairly complete |
| implementation of Cisco HDLC and a minimal implementation of |
| PPP. The longer term goal is to switch the PPP layer to the |
| generic PPP interface that is new in Linux 2.3.x. The API should |
| remain unchanged when this is done, but support will then be |
| available for IPX, compression and other PPP features |

| Currently we do not end all packets with the correct Cisco multicast |

| be corrected. |
