Steps to reproduce the behavior

lspci
0b:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

tried changing channels, iw reg set region, moving around bridge and interfaces, "wds" and "4addr" settings i found. reverting to 2.9 allows AP to start.

Pretty sure this is a hostapd, firmware or kernel bug (or a combination or all three? i can't keep up with wifi on linux, swear something changes every time a dev sneezes thinking of wifi). But I have tried everything at this point, hostapd-2.10 is broken.

Found a uh, workaround. Hardware works mostly, hostapd "works" mostly. So I have to assume it's a "fix" in 2.10 and firmware that's labeling things as not-usable when they damn well are and should be. lil mad. closing.
