Is it me or the current patch for Raspberry pi 4/Raspbian OS 64 bit is not available (bcm43455c0/7_45_241)

Hi,
When following some tutorials for patching wifi chipset for raspberry pi, I dont' manage to do it with my rpi4 running raspbian 64bits:

pi@raspberrypi:~/Dev/nexmon $ uname -a
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux
pi@raspberrypi:~/Dev/nexmon $ ethtool -i wlan0

pi@raspberrypi:~/Dev/nexmon $ lsb_release -a
No LSB modules are available.

So inside nexmon/patches/bcm43455c0/7_45_241 there is only one file and
make backup-firmware/make install-firmware don't exist ...

We currently don't provide a patch for the firmware version 7.45.241.
But you can try to go with version 7.45.206 for now, however, be aware that there is a known problem with frame injection that sometimes leads to a crash.
