Alexis Bauvin 6a6d6681ac l3mdev: add function to retreive upper master ... Existing functions to retreive the l3mdev of a device did not walk the master chain to find the upper master. This patch adds a function to find the l3mdev, even indirect through e.g. a bridge: +----------+ | | | vrf-blue | | | +----+-----+ | | +----+-----+ | | | br-blue | | | +----+-----+ | | +----+-----+ | | | eth0 | | | +----------+ This will properly resolve the l3mdev of eth0 to vrf-blue.
