Quite interesting; Google knows nothing about these devices that I can
find.  What platform are these based on?

But in any case, since these blocks are almost identical to the DW5550
block, maybe update the comments to indicate that they need NOARP
unlike the MBM platform that the 5550 is based on?

There are a number of launchpad bugs reported for these devices.  Don't
know why they chose that channel..  This one:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520147
shows that it is an Intel/Infineon based design.

BTW, DeWalt seems to own these device names :)

those devices are still in the testing stage, so there is nothing
about them in the web. They are Infineon based.

Sure, I can do a V2 patch for that.

patches were passed first to Canonical for custom OS image testing.

413c:81ba is the HSPA+ variant of the family: however this does not
use ncm, but ecm, see
