From c50b2883dfc1ce355dc37238741ef97cd2c5d000 Mon Sep 17 00:00:00 2001 From: Patrick Wildt Date: Thu, 3 Oct 2019 13:48:47 +0200 Subject: nvme: add accessor to namespace id and eui64 This adds a function which can be used by e.g. EFI to retrieve the namespace identifier and EUI64. For that it adds the EUI64 to its driver internal namespace structure and copies the EUI64 during namespace identification.
