Subject: [PATCH 1/2] libnl: add libnl-cli library

Hi,

this has formal issues (like entirely missing commit message, missing SoB, 
...). Please have another look at https://openwrt.org/submitting-patches
Hey,


thanks for your quick response to my first submission. I'll fix that.

Apart from that, do we need this in the main repo or could it also go into 
packages?

Whether libteam belongs to the main repo or package may be subject to point of 
view.



My perspective is that we are working on *hardware enablement* here. At least 
some switch chips support Link Aggregation in addition to hardware switching 
and VLAN filtering. This will be handled by offloading the LAG configuration 
from the kernel team driver.



The intended functionality consists of:



  * Team module for netifd
 (package already in main)
      - Submitted: 
https://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033269.html

  * The libteam package to support the team module (new package)
      - Submitted in PATCH 2/2.

  * A change in libnl to support the libteam package (package already in main)
      - Submitted in PATCH 1/2.

  * The kernel team driver (already in kernel)
      - Works as expected.

  * Offloaded LAG confugration to a switch driver (to be done in kernel)
      - This is of course hardware specific.

I would rather see all support protocols for switch chip features (like RSTP 
and LACP) ready in the main repo and supported by netifd and the network UCI 
configuration. What is the motivation to keep these networking features 
separate?

Cheers

Pavel Šimerda

Best
