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:
Currently, NetworkManager only allows to specify devices by name or MAC address. Since the device name is not stable and the MAC address requires an inventory about which MAC addresses are used, it would be nice to be able to specify a network card by PCI address, i.e. 0000:00:1f.6.
Additional info:
This could be implemented by a match setting that already exists for interface-name but not yet for PCI ID.
there is:
- grep PCI_SLOT_NAME /sys/class/net/*/device/uevent
- ethtool -i eth0
- which uses ETHTOOL_GDRVINFO and "struct ethtool_drvinfo"
- udevadm info -a -p /sys/class/net/eth0
- sudo lshw -c network -businfo
- lspci -D
- udevadm info /sys/class/net/eth0
Note in `man systemd.link` there is:
Path=
A whitespace-separated list of shell-style globs matching the persistent path, as exposed by the udev property "ID_PATH".
and
$ udevadm info /sys/class/net/eth0 | grep ID_PATH=
So, we probably want to implement this udev "path".
