# packet.transport.rdmap(3)

RDMAP module

## NAME

packet.transport.rdmap - RDMAP module

## DESCRIPTION

Decode RDMAP layer.

RFC 5040 Remote Direct Memory Access Protocol Specification

## CLASSES

### class OpCode(packet.utils.Enum)

```
enum OpCode
```

### class RDMAP(baseobj.BaseObj)

```
RDMAP object
Usage:
    from packet.transport.rdmap import RDMAP
    x = RDMAP(pktt, pinfo)
Object definition:
RDMAP(
    version = int,  # RDMA Protocol version
    opcode  = int,  # RDMA OpCode
    psize   = int,  # Payload Size
    [ # Only valid for Send with Invalidate and Send with Solicited Event
      # and Invalidate Messages
        istag = int,  # Invalidate STag
    ]
    [ # RDMA Read Request Header
        sinkstag = int,  # Data Sink STag
        sinksto  = int,  # Data Sink Tagged Offset
        dma_len  = int,  # RDMA Read Message Size
        srcstag  = int,  # Data Source STag
        srcsto   = int,  # Data Source Tagged Offset
    ]
)
```

**Methods defined here:** ---------------------

**\_\_init\_\_(self, pktt, pinfo)** Constructor

Initialize object's private data.

- **pktt:**

  Packet trace object (packet.pktt.Pktt) so this layer has access to the parent layers.

- **pinfo:**

  List of two integers: \[RDMAP control, Invalidate STag\].
