If a bond interface is deleted and recreated, the gratuitous ARPs are sent with the wrong MAC address

[xavier]

When an interface is added to a bond interface, if it is the first
interface added, the MAC address of the bond interface is changed
to the MAC address of the added interface. When subsequent interfaces
are added, their MAC addresses are changed to that of the bond
interface.

Uptream issue [0] identified that if a bond interface is deleted and
recreated, the gratuitous ARPs were sent with the wrong source MAC
address.

Upstream commit [1] updates interface MAC addresses from the
netlink RTM_NEWLINK messages, so that the correct MAC address
is always used.

Thank you for taking the time to report this bug and helping to make Ubuntu better. What you need is a Stable Release Upgrade (SRU), which is subject to the procedure and policy documented here:

  https://wiki.ubuntu.com/StableReleaseUpdates

SRUs always come with some regression risk, so a compelling use case currently broken by the bug is normally needed to counterweight this risk. This is what we may be missing in this case. If you want to help the process please comment with a justification against https://wiki.ubuntu.com/StableReleaseUpdates#When and complete steps 1 through 4 in https://wiki.ubuntu.com/StableReleaseUpdates#Procedure - and go ahead with all the steps if you can. Note that that SRU team would need to make a final decision.

The first upstream version including the fix is v2.0.13, not yet in Debian as of today.
