The Package Makefile for backports is located here:
package/kernel/mac80211/Makefile

We backported some patches from more recent version, but the one you
linked is missing as far as I know. Please send a patch if you need it
so we can add it.

I think I also saw this once or twice, please report this upstream. Are
you using ath10k-ct driver which is still based on Linux 4.19 or do you
use the normal ath10k driver?

My plan is to update the wireless subsystem to the one from Linux 5.4 in
about 4 weeks in OpenWrt master. Kernel 5.4 should be a LTS kernel so we
can follow that one and get security and other updates for the next few
years. OpenWrt 19.07 will stay at the wireless subsystem of Linux 4.19
and will get updated to the most recent 4.19 stable version every few
months.
