- * Linked list of created PPPoS interfaces
- *
- * We only need to keep track of existing PPPoS interfaces if PPPoS
- * is not the only enabled protocol.
- *
- * PPP CORE does not have callbacks pointers for all PPPoS callbacks
- * which should actually be required for PPPoS (VJ config, asyncmap, ...),
- * there is too much callbacks to create and PPPoS must be kept light,
- * especially for users who are only using PPPoS.
- *
- * But there is a drawback, PPP CORE does not know which
- * lower protocols it is talking to thanks to the abstraction,
- * therefore if PPPoS is enabled as well as PPPoE or PPPoL2TP there
- * might be situation where PPP CORE calls pppos_ config functions
- * on interfaces which are NOT PPPoS one. This is very unlikely to
- * happen because protocols not supported by PPPoE or PPPoL2TP are
- * disabled at LCP/IPCP negotiation but we are better safe than sorry.
- *
- * So we check if passed PPP pointer to PPPoS configuration functions
- * is a PPPoS interface by checking against a linked list of existing
- * PPPoS interfaces.
