Right.

Note that I only did that for purposes of software AP. This is router
which provides both wired and wireless network connectivity, which are
bridged for network uniformity (no routing, broadcast and multicast
passing, no dhcp forwarding trickery and so on).

I can show you configuration but it doesn't mean that it would work for
you with wireless NIC not in AP mode. That said, if THIS way won't work
for you, it doesn't mean it's impossible at all: try Open vSwitch! It is
much more agile compared to standard linux bridging, especially in areas
related to bridging between multiple interfaces created on the fly,
VLANs and such, making it very useful on virtualization hosts.

I set up bridge in NM with nmtui. You can find guides on setting it up
with NM GUI / nmcli combo, e.g.
https://www.happyassassin.net/2014/07/23/bridged-networking-for-libvirt-with-networkmanager-2014-fedora-21/
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Network_Bridging_Using_the_NetworkManager_Command_Line_Tool_nmcli.html

NM creates bridge0 and adds eth0 to it, sets up IPs and such after that.
Wireless device wlan0 is set up much later, and hostapd adds wlan0 to
that bridge after it finishes configuring wireless lan. It's impossible
to add uncofigured wlan0 device to bridge.

Either way, the resulting configuration files look like

$ cat /etc/sysconfig/network-scripts/ifcfg-bridge0
DEVICE=bridge0
STP=no
TYPE=Bridge
BOOTPROTO=none
DNS1=127.0.0.1
DOMAIN=asgard
DEFROUTE=no
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=<removed>
IPV6_DEFROUTE=no
IPV6_FAILURE_FATAL=no
NAME=bridge0
UUID=c10629d4-3fc8-4987-98d2-b82799419e49
ONBOOT=yes
IPADDR=192.168.2.1
PREFIX=24

$ cat /etc/sysconfig/network-scripts/ifcfg-bridge0_eth0 
TYPE=Ethernet
NAME=bridge0_eth0
UUID=a3810633-5171-4946-9e60-f3a09bd7f4e7
DEVICE=eth0
ONBOOT=yes
BRIDGE=c10629d4-3fc8-4987-98d2-b82799419e49


I won't publish the whole hostapd.conf file, related lines are

interface=wlan0
bridge=bridge0


As for the log file, here are the lines related to eth0/wlan0/bridge0
initialization:
