Subject[PATCH] [30/139] qla2xxx: Populate Command Type 6 LUN field properly.
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Mike Hernandez <michael.hernandez@qlogic.com>

commit 85727e1f78bd8392a0657ad6a4ff85fef1cc4a6d upstream.

Use the host_to_fcp_swap call to correctly populate the LUN field
in the Command Type 6 path. This field is used during LUN reset
cleanup and must match the field used in the FCP command.
