Subject: [PATCH v4 21/24] smb: move smb_sockaddr_in and smb_sockaddr_in6 to common/smb2pdu.h
From: ZhangGuoDong <zhangguodong@...inos.cn>
Rename 4 places:
- iface_info_ipv4 -> smb_sockaddr_in
- iface_info_ipv6 -> smb_sockaddr_in6
- IPv4address -> IPv4Address
- IPv6address -> IPv6Address
Then move duplicate definitions to common header file.
