There is no single answer to this. Lots of the home routing SoC space is
now converging on 4.4, but BCM decided to go for 4.1. They came from 3.2,
3.4 and perhaps 3.10. When I talk to staff at SoC vendors, they seem to
live in a world where you take a linux kernel that's announced as LTS (in
the best of worlds), work on that for 1-2 years during which you release
an SDK, which then the device manufacturers will take and start putting
their solutions on, which takes another 1-2 years before it reaches
customers. So already there is significant latency.
This doesn't mean there are not devices out there today, newly installed,
that have really ancient kernels (as you have discovered). This is
especially true for cheaper and simpler devices that are very cost
There is movement in the right direction, but revving kernels on older
platforms is still hard, as in all of IoT space, due to lack of revenue
from older platforms. Main model is still to sell a device and then there
is no further income, so no money to continously develop the device.
