LAN clamped at 100Mbps on Smart Hub Plus

When I plug my linux laptop into a cheap gigabit switch it shows 1Gbps in ethtool. When I plug it into the Smart Hub Plus it shows 100Mbps.

This router is advertised as having 1Gbps LAN ports. If that's physically true but the firmware clamps them at a tenth of that speed, the router should be advertised accordingly.

100Mbps is slower than fibre broadband and people want to use ethernet for its stability, so this undermines the speed claims of the higher-priced broadband deals.

Is there a workaround or setting to fix this, or can I look forward to a firmware update?

I would suggest that the SH+ hub has some mechanism that throttles for cable length or perhaps when a switch is added. 

Definitely not as black and white as the presence of a switch. I have a switch connected to the LAN port of an SH3, with another two switches daisy chained to that, and an Ethernet device at the end of the link is able to negotiate at 1GbE.
