Bug Description

SMC is currently limited to traffic within a single IP subnet only. SMC v2 will lift this restriction, which also (confusingly) applies to ISM devices/SMC-D.
This is a strict requirement e.g. for Docker containers.
Current planning is to have a new ISM device type, titled "ISM v2" for now, so users can make a conscious decision whether (conceptually) different IP subnets can be interconnected or not, which might be a security concern.

Business value:
Prerequisite for proper Docker support

Did this landed in 5.8 or does it need to be moved to 21.04 now?

Feature is an important one, even only the kernel part.
Once available, we will than ask for a feature freeze exception.

Since this is a kernel topic, there is still a little change to get it in, if it arrives prior to the kernel freeze - ideally by the end of September!
Once the kernel freeze is in effect, the entire release is in frozen too ...

Feature moved to 21.04, will not make it in time for 20.10. But has the potential, to be requested via SRU for 20.10,20.04 in addition to 21.04.
