Subject: [PATCH v5 07/14] smb: move some duplicate definitions to common/smb2pdu.h
From: ZhangGuoDong <zhangguodong@...inos.cn>
In order to maintain the code more easily, move duplicate definitions to
common header file.
There are only 4 different definitions, the client uses cpu_to_le16()
but the server does not:
- RSS_CAPABLE
- RDMA_CAPABLE
- INTERNETWORK
- INTERNETWORKV6
The other definitions are exactly the same on both client and server.
The struct smb_hdr is defined in MS-CIFS and MS-SMB, but it's also used by
SMB2 and SMB3, so move it to the common smb2pdu.h.
