The longer term goal is to switch the PPP layer to the 62 generic PPP interface that is new in Linux 2.3.x. The API should 63 remain unchanged when this is done, but support will then be 64 available for IPX, compression and other PPP features 65 </para> 66 </chapter> 67 <chapter id="bugs"> 68 <title>Known Bugs And Assumptions</title> 69 <para> 70 <variablelist> 71 <varlistentry><term>PPP is minimal</term> 72 <listitem> 73 <para> 74 The current PPP implementation is very basic, although sufficient 75 for most wan usages. 76 </para> 77 </listitem></varlistentry> 78 79 <varlistentry><term>Cisco HDLC Quirks</term> 80 <listitem> 81 <para> 82 Currently we do not end all packets with the correct Cisco multicast 83 or unicast flags.
