just an update

We have tried different fwupdate packages (and required dependencies) from a lot of Linux OS (mostly from opensuse) and Suse terminal is finally accepting the "fwupdate" command.

Only problem is :
Result of fwupdate -s

it says update is not supported? [we have tried different systems and got same result]

upon checking the c files for fwupdate library, [ Here and Here ] i found out that it is caused by ESRT not enabled or present .

Using this info, i checked online and learned that ESRT is supported starting Linux 4.2 kernel cycle.
I checked SLED SP3 using "uname -r" command and got 4.4.73-5-default

is there anyone who successfully updated their FW on SLED SP3?
