ipv6: sr: add option to control lwtunnel support
This patch adds a new option CONFIG_IPV6_SEG6_LWTUNNEL to enable/disable support of encapsulation with the lightweight tunnels. When this option is enabled, CONFIG_LWTUNNEL is automatically selected. Fix commit 6c8702c60b88 ("ipv6: sr: add support for SRH encapsulation and injection with lwtunnels") Without a proper option to control lwtunnel support for SR-IPv6, if CONFIG_LWTUNNEL=n then the IPv6 initialization fails as a consequence of seg6_iptunnel_init() failure with EOPNOTSUPP: NET: Registered protocol family 10 IPv6: Attempt to unregister permanent protocol 6 IPv6: Attempt to unregister permanent protocol 136 IPv6: Attempt to unregister permanent protocol 17 NET: Unregistered protocol family 10 Tested (compiling, booting, and loading ipv6 module when relevant) with possible combinations of CONFIG_IPV6={y,m,n}, CONFIG_IPV6_SEG6_LWTUNNEL={y,n} and CONFIG_LWTUNNEL={y,n}.
