Author: dab Date: Mon Sep 21 15:45:49 2020 New Revision: 365948 URL: https://svnweb.freebsd.org/changeset/base/365948 Log: Honor the FWUG value of some drives in nvmecontrol nvmecontrol tries to upload firmware in chunks as large as it thinks the device permits. It fails to take into account the FWUG value used by some drives to advertise the size and alignment limits for firmware chunks. - Use the firwmare update granularity value from the - If the granularity is not reported or not restricted, fall back to the previously existing logic that calculates the max transfer size based on MDTS. - Add firmware update granularity to the identify-controller output.
