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

for most wan usages.

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.
