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

or unicast flags. Nothing appears to mind too much but this should

be corrected.
