Which hardware is this? OpenWrt / ath10k will not work on Archer C7v1. That first version of the chip has silicon bugs that the developers were unwilling to work around, so they abandoned it.
The bridge patch only affects clients. The unpatched kernel still worked on APs.
While dusty memories, I still recall being very happy that I didn't buy a C7v1 when they were introduced because of the lack of open-source driver support. As far as I know, the C7V1's chip revision still isn't (and never will be) supported for 5 GHz.
