%description
This package provides the %{pkg} driver. Compared to the in-kernel driver this
driver re-enables support for deprecated BladeEngine 2 and 3 adapters.

BladeEngine 2 (BE2) devices:
- 0x19A2:0x0211: Emulex BladeEngine 2 Network Adapter
- 0x19A2:0x0700: Emulex OneConnect Tigershark NIC

BladeEngine 3 (BE3) devices:
- 0x19A2:0x0221: Emulex BladeEngine3 Network Adapter
- 0x19A2:0x0710: Emulex OneConnect Tomcat NIC
