windows socket ipv6 SOCK_RAW

bind处一直报错WSAEADDRNOTAVAIL10049，不知道为什么？

WSAEADDRNOTAVAIL 10049

Cannot assign requested address.

The requested address is not valid in its context. This normally results from an attempt to
bind to an address that is not valid for the local computer. This can also result from
connect,
sendto,
WSAConnect,
WSAJoinLeaf, or
WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0).

IPv4版本，需要保证本地连接已接通

IPv6版本，2000::2可以通，addrfrom.sin6_scope_id = 0;地址范围设置是必须的，若为unicast地址可以设置为0。需要赋值，不然内存默认可能为cc。
