ipvlan: Support bonding events

champtar · NipaLocal · commit e78c0ccd7029 · 2025-01-09T04:01:20.000-08:00
This allows ipvlan to function properly on top of bonds using active-backup mode. This was implemented for macvlan in 2014 in commit 4c99125 ("macvlan: Support bonding events"). Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com> Signed-off-by: NipaLocal <nipa@local>
