[lwip-devel] [bug #27858] PPP: missing call to netif_set_down()

[Simon Goldschmidt]

Follow-up Comment #1, bug #27858 (project lwip):

I think this is a more generic problem when working with netif callbacks and
it should be solved in netif_remove(), i.e. resetting NETIF_FLAG_UP and
calling NETIF_STATUS_CALLBACK() in netif_remove().

It's a sad thing that the (relatively) new netif-callbacks don't have a
reason-argument which we can use to indicate that we remove the netif.
