When IPv6 is prefered it will choose a link local address on a network
that lacks IPv6 over a working IPv4 network, breaking networking.
Change this behaviour to prefer a link local address only as a last
resort.
This also changes LWIP::get_ipv6_addr to not return link local
addresses. Use get_ipv6_link_local_addr instead for this.
This patch contains improvements mentioned in the unresolved PR
comments:
- function names were changed from socket_sendmsg/socket_recvmsg to
socket_sendto_control/socket_recvfrom_control.
- default implementation of this functions was provided in the
NetworkStack class.
- MsgHeaderIterator accesses elements on the aligned addresses.
Add license identifier to files which Arm owns the copyright to,
and contain either BSD-3 or Apache-2.0 licenses. This is to address
license errors raised by scancode analysis.
- Public headers moved into mbed-os/connectivity/lwipstack/include/lwipstack folder
- Source moved into mbed-os/connectivity/lwipstack/source folder
- Internal lwip and lwip-sys libraries moved to source folder
