[openib-general] [PATCH 05/17] ehca: InfiniBand query and multicast functionality

[Heiko J Schick]

Hello Hal,

we don't have a fw_ver which is available for our adapter.
The be compatible with the OpenIB stack we copy the hw_ver
into the fw_her. The hw_ver alredy has a device file.

If it is necessary, I can add a file for the fw_ver too, but
this will include the same data as is in the hw_ver file.

Regards,
	Heiko
