Description David Critch 2021-05-12 16:43:35 UTC
Description of problem:
We have a customer that needs to use bonding mode balance-alb, with the tlb_dynamic_lb setting set to 0. This device is configured via NetworkManager. After creating the bond, tlb_dynamic_lb is still set to 1.

Version-Release number of selected component (if applicable):
NetworkManager-1.30.0-1.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a bond, e.g.:
nmcli conn add type bond ifname bond0 con-name bond0 bond.options "mode=balance-alb,miimon=100,xmit_hash_policy=5,tlb_dynamic_lb=0" master brcnv connection.autoconnect no
2. cat /sys/class/net/bond0/bonding/tlb_dynamic_lb


Actual results:
$ cat /sys/class/net/bond0/bonding/tlb_dynamic_lb 
1


Expected results:
$ cat /sys/class/net/bond0/bonding/tlb_dynamic_lb 
0
