14 <https://en.wikipedia.org/wiki/Point-to-Point_Protocol>`_ (PPP) is a data link
16 between two nodes. PPP is used over many types of serial links since IP packets
20 In Zephyr, each individual PPP link is modelled as a network interface. This
21 is similar to how Linux implements PPP.
23 PPP support must be enabled at compile time by setting option
25 The PPP implementation supports only these protocols:
