Message:

AsyncCompletion: Move bandwidth groups to the generic code and support arbitrary grouping of endpoints into bandwidth groups.

To add a new bandwidth group use setextradata (this adds a group called Test and sets the maximum to 2 MB/s):

VBoxInternal/PDM/AsyncCompletion/File/BwGroups/Test/Max 2097152
VBoxInternal/PDM/AsyncCompletion/File/BwGroups/Test/Start 2097152
VBoxInternal/PDM/AsyncCompletion/File/BwGroups/Test/Step 0

To assign a disk to the group add:

VBoxInternal/Devices/ahci/0/LUN#0/AttachedDriver/Config/BwGroup Test
