Subject: ipv6: fix source routing

From: Sabrina Dubroca <[email protected]>

[ Upstream commit ec9c4215fef37da6668c4105f5ad3891aaa6527a ]

Commit a149e7c7ce81 ("ipv6: sr: add support for SRH injection through setsockopt") introduced handling of IPV6_SRCRT_TYPE_4, but at the same time restricted it to only IPV6_SRCRT_TYPE_0 and IPV6_SRCRT_TYPE_4. Previously, ipv6_push_exthdr() and fl6_update_dst() would also handle other values (ie STRICT and TYPE_2).

Restore previous source routing behavior, by handling IPV6_SRCRT_STRICT and IPV6_SRCRT_TYPE_2 the same way as IPV6_SRCRT_TYPE_0 in ipv6_push_exthdr() and fl6_update_dst().
