From ac01bbbd3b7ebfca64357aed12cf476b16abe3ce Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 19 Oct 2005 20:01:17 +0200 Subject: [SCSI] sas: add flag for locally attached PHYs Add a flag to mark a PHY as attached to the HBA as opposed to beeing on an expander. This is needed because various features are only supported on those. This is a crude hack, the proper fix would be to use different classes for host-attached vs expander phys. I'm looking into that.
