According to RFC 7609, all CLC messages contain a peer ID that consists of a unique instance ID and the MAC address of one of the host's RoCE devices. But if a SMC-R connection cannot be established, e.g., because no matching pnet table entry is found, the current implementation uses a zero value in the CLC decline message although the host's peer ID is set to a proper value. If no RoCE and no ISM device is usable for a connection, there is no LGR and the LGR check in smc_clc_send_decline() prevents that the peer ID is copied into the CLC decline message for both SMC-D and SMC-R. So, this patch modifies the check to also accept the case of no LGR. Also, only a valid peer ID is copied into the decline message. Signed-off-by: Hans Wippel <ndev@hwipl.net> Signed-off-by: David S.
