From 88edf74610bd894b93438f389688bc8b4a2d3414 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 6 Sep 2006 17:36:13 -0500 Subject: [PATCH] [SCSI] SAS: consolidate linkspeed definitions At the moment we have two separate linkspeed enumerations covering roughly the same values. This patch consolidates on a single one enum sas_linkspeed in scsi_transport_sas.h and uses it everywhere in the aic94xx driver. Eventually I'll get around to removing the duplicated fields in asd_sas_phy and sas_phy ...
