uqmi: Add proper IPv6 support
Use the new --ip-family option to start both IPv4 and IPv6 sessions by default. Autoconnect can't be used when starting two sessions, so revert back to using the client IDs and packet data handles for handling the network connection. Some modem firmwares do not implement a RA server, therefore by default use outband IP configuration and static addressing. Some other firmwares report bogus IP configuration with the WDS get current settings command. In this case inband configuration with DHCP/RA can be optionally enabled by setting option dhcp to 1. Per 3GPP standard a /64 prefix is served to all clients, which is extended to LAN as specified in RFC 7278. v2: Restrict the IPv6 gateway route source address Signed-off-by: Matti Laakso <malaakso@elisanet.fi> SVN-Revision: 46843
