After this package is added the system is to be rebooted to incluse the new driver in the system kernel. The old drivers will be saved in the directories /var/sadm/pkg/ptf122/etc/conf/pack.d/asyc and /var/sadm/ptf122/etc/conf/pack.d/iasy . In case if the package can not be removed using pkgrm, restore the system by copying Driver.o from the above specified directory to /etc/conf/pack.d/asyc. And also the directory /var/sadm/pkg/ptf122" is to be removed from the system. Then the kernel is to be rebuilt and the system is to be rebooted with new kernel.
