Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Description of problem:
we need more man entries for sriov functionality. nm-settings to list all possible features and nmcli-examples to see how nmcli do expect the stuff to be configured. 

Version-Release number of selected component (if applicable):
1.14.0-7

semicolor-separated should be semicolon in vfs man nm-settings description

Example added:

           $ nmcli con add type ethernet con-name EthernetPF ifname em1
           $ nmcli con modify EthernetPF sriov.total-vfs 3 sriov.autoprobe-drivers false
           $ nmcli con modify EthernetPF sriov.vfs '0 mac=00:11:22:33:44:55 vlans=10, 1 trust=true spoof-check=false'
           $ nmcli con modify EthernetPF +sriov.vfs '2 max-tx-rate=20'

       This example demonstrates adding an Ethernet connection for physical function (PF) ens4 and configuring 3 SR-IOV virtual functions (VFs) on it. The first VF is configured with MAC address
       00:11:22:33:44:55 and VLAN 10, the second one has the trust and spoof-check features respectively enabled and disabled. VF number 2 has a maximux transmission rate of 20Mbps. The kernel is
       instructed to not automatically instantiate a network interface for the VFs.
