parentnet: phylink: ensure inband AN works correctly (diff)
ipv6: Consider sk_bound_dev_if when binding a raw socket to an address
IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set.
