From c6e0c925064cbff2cf36f590d14641cfdf02f473 Mon Sep 17 00:00:00 2001 From: Dick Kennedy Date: Wed, 23 Aug 2017 16:55:43 -0700 Subject: [PATCH] scsi: lpfc: Fix relative offset error on large nvmet target ios If the nvmet_fc transport breaks an io into multiple sequences, the driver will improperly set the relative offset on the 2nd through N sequences. Correct by properly formatting the hw cmd so the relative offset is picked up from the hw cmd.
