Re: [PATCH 0/2] Migrate QRTR Nameservice to Kernel

Hello,

This patchset migrates the Qualcomm IPC Router (QRTR) Nameservice
from userspace
to kernel under net/qrtr.

The userspace implementation of it can be found here:
https://github.com/andersson/qrtr/blob/master/src/ns.c

This change is required for enabling the WiFi functionality of some
Qualcomm
WLAN devices using ATH11K without any dependency on a userspace
daemon.

Just out of curiousity, what's the motivation for not requiring a
userspace daemon? What are the downsides of the current userspace
daemon implementation?

Dan

The original userspace code is published under BSD3 license. For
migrating it
to Linux kernel, I have adapted Dual BSD/GPL license.

This patchset has been verified on Dragonboard410c and Intel NUC with
QCA6390
WLAN device.

Thanks,
Mani
