 When using FI_HMEM for AWS Neuron or Habana SynapseAI buffers, the provider
 requires peer to peer transaction support between the EFA and the FI_HMEM
 device. Therefore, the FI_HMEM_P2P_DISABLED option is not supported by the EFA

+On the receiver side, it will post the user recv buffer to the user recv QP directly when the user
+calls fi_recv(). Currently such receive cannot be cancelled and fi_cancel() is not supported in
+zero-copy receive mode.
 If a receiver gets RTM packets delivered to its default QP, it raises an error
 because it requests all RTM packets must be delivered to its user recv QP.
