| .TH UMAD_REGISTER2 3 "March 25, 2014" "OpenIB" "OpenIB Programmer's Manual" |
| .SH "NAME" |
| umad_register2 \- register the specified management class and version for port |
| .SH "SYNOPSIS" |
| .nf |
| .B #include <infiniband/umad.h> |

| .BI "int umad_register2(int " "port_fd" ", struct umad_reg_attr *" "attr" ", uint32_t *" "agent_id"); |
| .fi |
| .SH "DESCRIPTION" |
| .B umad_register2() |
| registers for a MAD agent using the provided registration attributes |
| |
| .I port_fd\fR |
| the port on which to register the agent |
| |
| .I attr\fR |
| The registration attributes as defined by the structure passed. See below for details of this structure. |
| |
| .I agent_id\fR |
| returned on success. agent_id identifies the kernel MAD agent a MAD is received by or to be sent by. agent_id is returned in the umad header "struct ib_user_mad" on recv and specified in umad_send when sending. |

| .SH "REGISTRATION ATTRIBUTE STRUCTURE" |
| .nf |
| struct umad_reg_attr { |
| .in +8 |
| uint8_t mgmt_class; |
| uint8_t mgmt_class_version; |
| uint32_t flags; |
| uint64_t method_mask[2]; |
| uint32_t oui; |
| uint8_t rmpp_version; |
| .in -8 |
| }; |
| |
| .I mgmt_class\fR |
| Management class to register for. |
| |
| .I mgmt_class_version\fR |
| Management class version to register for. |
| |
| .I flags\fR |
| Registration flags. If a flag specified is not supported by the kernel, |
| an error is returned, and the supported flags are returned in this field. |
| |
| .P |
| Current flags are: |
| .in +8 |
| UMAD_USER_RMPP -- flag to indicate the kernel should not process |
| RMPP packets. All RMPP packets will be treated like individual |
| MADs. The user is responsible for implementing the RMPP |
| protocol. |
| .in -8 |
| |
| .I method_mask\fR |
| A bit mask which indicates which unsolicited methods this agent should |
| receive. Setting this array to 0 will result in the agent only |
| receiving response MADs for which a request was sent. |
| |
| .I oui\fR |
| The oui (in host order) to use for vendor classes 0x30 - 0x4f. |
| Otherwise ignored. |
| |
| .I rmpp_version\fR |
| If the class supports RMPP and kernel RMPP is enabled (the default) |
| indicate which rmpp_version to use. |
| |
| |
| .SH "RETURN VALUE" |
| .B umad_register2() |
| returns 0 on success and +ERRNO on failure. |
