* Windows uses 4280 (the max xmit/recv size negotiated on DCERPC).
* This is fits into the max_xmit negotiated at the SMB layer.
*
* On the sending side they may use SMBtranss if the request does not
* fit into a single SMBtrans call.
*
* Windows uses 1024 as max data size of a SMBtrans request and then
* possibly reads the rest of the DCERPC fragment (up to 3256 bytes)
* via a SMBreadX.
*
* For now we just ask for the full 4280 bytes (max data size) in the SMBtrans
* request to get the whole fragment at once (like samba 3.5.x and below did.
*
* It is important that we use do SMBwriteX with the size of a full fragment,
* otherwise we may get NT_STATUS_PIPE_BUSY on the SMBtrans request
* from NT4 servers. (See bug #8195)
