RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:
.The `balance-slb` bonding mode is now supported The new `balance-slb` bonding mode Source load balancing requires no switch configuration. The `balance-slb` divides traffic on the source Ethernet address using `xmit_hash_policy`=`vlan+srcmac`, and NetworkManager adds necessary `nftables` rules for traffic filtering. As a result, you can now create bond profiles with the `balance-slb` option enabled by using NetworkManager.

Comment 1 Gris Ge 2022-11-03 06:34:32 UTC 
Patch send to upstream: https://github.com/nmstate/nmstate/pull/2082

Example yaml:

```yml
---
interfaces:
- name: bond99
  type: bond
  state: up
  link-aggregation:
    mode: balance-xor
    options:
      xmit_hash_policy: "vlan+srcmac"
      balance-slb: 1
```



This is userspace bond option. You need updated NetworkManager, nftables and kernel. Nmstate only set `balanace-slb=1` to NM connection, not verifying its functionality. `nmcli c show` might indicate connection failed to activate due to errors of use space tools.

To test, checking output of `nmcli --fields bond.options c show <bond_conntion_id>` is enough.
