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

Should there also be a /sys/class/infiniband/ehca<n>/fw_ver file created
as well ?
