lwIP seems to lose track of the sa_family for the socket internally, when lwip_connect()
|
|
is called, it thus receives an AF_UNSPEC socket which fails. Here we use lwIP's own facilities
|
|
to get the sa_family ourselves and rebuild the address structure and pass it to lwip_connect().

I suspect this is due to a struct memory alignment issue or my own misuse of the API */
