From 721b3917c4ae222085c6de70c24b73b0e7950b35 Mon Sep 17 00:00:00 2001 From: James Smart Date: Fri, 21 Oct 2016 23:33:34 +0300 Subject: [PATCH] nvme-fabrics: set sqe.command_id in core not transports Currently, core.c sets command_id only on rd/wr commands, leaving it to the transport to set it again to ensure the request had a command id. Move location of set in core so applies to all commands. Remove transport sets.
