In IPv6, the default gateway and prefix length are determined by receiving a router advertisement as defined in - https://www.rfc-editor.org/rfc/rfc4861.
Add support for sending router solicitation (RS) and processing router advertisements (RA).
If the RA has prefix info option and following conditions are met, then gatewayip6 and net_prefix_length of ip6addr env variables are initialized. These are later consumed by IPv6 code for non-local destination IP.
- "Router Lifetime" != 0
- Prefix is NOT link-local prefix (0xfe80::/10)
- L flag is 1
- "Valid Lifetime" != 0
Timing Parameters:
- MAX_RTR_SOLICITATION_DELAY (0-1s)
- RTR_SOLICITATION_INTERVAL (4s) (min retransmit delay)
- MAX_RTR_SOLICITATIONS (3 RS transmissions)
The functionality is enabled by CONFIG_IPV6_ROUTER_DISCOVERY and invoked automatically from net_init_loop().
