Which mrsas drivers are available?

There are two different mr_sas drivers: one comes with Oracle Solaris and one is provided by LSI. Both versions are installed as a package. This is the Oracle package:

The key indicator is that the kernel function scsi_hba_probe_pi() which is called by mr_sas:mrsas_config_ld(),  allocated kernel memory via kmem_alloc(), and then the same function mr_sas:mrsas_config_ld() frees it via kmem_free().
