[SRU Request] bonding: arp monitoring is failing with tuntap interfaces

[Nicolas Dichtel]

Hi Ubuntu kernel team,

please, could you consider to backport, up to bionic, the linux upstream commit
a31d27fbed5d ("tun: fix bonding active backup with arp monitoring"):

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a31d27fbed5d

It will be included in v5.16.

Here is the launchpad entry:

Thank you,
Nicolas
