802.11s channel width settings?

Hi all,

I'm using 802.11s to do mesh networking with ath10k on an OpenWRT
router. My throughput across the 802.11s connections is very low,
around 22 Mbits/s maximum. When I search my device with iw[1], I am
informed that the driver believes it is operating in 20MHz channels.
When I run it in AP mode, I get much faster speeds and iw claims the
interface is acting with an 80 MHz channel.

Is there any way to increase channel widths in 802.11s? If this is an
OpenWRT question and not ath10k I'll head over to the forums, but this
seemed more a driver issue as my wireless config requests wide
channels. Any chance there's a specific version of ath10k I should
push to?

Any information would be much appreciated, and I'll be happy to answer
any questions.
