From ecad0d2cb8a7997afdc95031ee3328b997aba5c4 Mon Sep 17 00:00:00 2001 From: James Smart Date: Mon, 23 Oct 2017 15:11:36 -0700 Subject: nvme-fc: remove NVME_FC_MAX_SEGMENTS The define is an arbitrary limit to the io size on the initiator, capping the io to 1MB-4KB. Remove the define from the transport. I/O size will solely be limited by the LLDD sg limits.
