RE: [lwip-users] bug #16602: PPP interface not reported as UP, so incoming packets are rejected.

Well, since sifdown() in ppp.c calls netif_remove(), calling netif_set_down() doesn't seem necessary. However, it might be added for clarification purposes, or perhaps for supporting future changes in the lwip core.

Guille,

Also, how about when calling sifdown() in ppp.c? I think this needs a call to netif_set_down() for similar reasons. What do you think?

Kind regards,
