>>>>>>>>>>>>>>>>>> README file for APAR IC15208 <<<<<<<<<<<<<<<<<<<<<<<<< Installation instructions:. This apar contains one changed part - AFINET.SYS. This part should be copied into the \MPTN\PROTOCOL directory. This part is a device driver that is loaded at boot time. Therefore after replacing the part, you must stop all programs and reboot the system for the new module to be loaded. Problem description: The hostid and hostname are being changed when loopback is enabled because the code only checked for adapter = 0 and loopback has adapter = 0. The code was changed to also check for the LOOPBACK flag.
