From 3b49fa807284ec30669a95fd5f3806e127d29f4d Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Mon, 3 Dec 2018 17:52:12 -0800 Subject: nvme-fabrics: allow user passing header digest Header digest is a nvme-tcp specific feature, but nothing prevents other transports reusing the concept so do not associate with tcp transport solely.
