%description
This package provides the Fusion MPT SAS Host (%{pkg}) driver.  Compared to the
in-kernel driver this driver is not restricted to the virtualization use case.
It supports the following adapters:

- 0x1000:0x0050: LSI SAS1064
- 0x1000:0x0054: LSI SAS1068
- 0x1000:0x0056: LSI SAS1064E
- 0x1000:0x0058: LSI SAS1068E
- 0x1000:0x0059: LSI SAS1068_820XELP
- 0x1000:0x0062: LSI SAS1078
