Abstract
A plurality of nodes are maintained in a switchless network, wherein each of the plurality of nodes has at least one host channel adapter for communication. A management datagram that indicates source to destination routes for communication in the plurality of nodes is provided. An attribute is configured in the management datagram to allow the management datagram to be propagated among the plurality of nodes of the switchless network without being terminated at host channel adapters.

1-20. (canceled)
A method, comprising:
- configuring, by a network driver of a first node, an attribute to indicate that transmission of a management datagram is not to be terminated by a host channel adapter of another node in a switchless network;
- transmitting by the network driver of the first node, the management datagram from the first node to a second node via a host channel adapter of the first node;
- and
- in response to determining by a host channel adapter of the second node that the attribute of the management datagram is configured to indicate that transmission of the management datagram is not to be terminated by the host channel adapter of the second node, transmitting the management datagram to a network driver of the second node.
A system in communication with a plurality of nodes in a switchless network, the system comprising:
- a memory of a node;
- and
- a processor of the node, the processor coupled to the memory, wherein the processor performs operations, the operations comprising:
- configuring, by a network driver of a first node, an attribute to indicate that transmission of a management datagram is not to be terminated by a host channel adapter of another node in a switchless network;
- transmitting by the network driver of the first node, the management datagram from the first node to a second node via a host channel adapter of the first node;
- and
- in response to determining by a host channel adapter of the second node that the attribute of the management datagram is configured to indicate that transmission of the management datagram is not to be terminated by the host channel adapter of the second node, transmitting the management datagram to a network driver of the second node.
A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations, the operations comprising:
- configuring, by a network driver of a first node, an attribute to indicate that transmission of a management datagram is not to be terminated by a host channel adapter of another node in a switchless network;
- transmitting by the network driver of the first node, the management datagram from the first node to a second node via a host channel adapter of the first node;
- and
- in response to determining by a host channel adapter of the second node that the attribute of the management datagram is configured to indicate that transmission of the management datagram is not to be terminated by the host channel adapter of the second node, transmitting the management datagram to a network driver of the second node.
