What does:
cat /proc/net/dev
and:
ls -l /sys/class/net
show in that case?

Does it work if you rmmod the network driver?

Firmware loading is implemented as a "fake kernel device". It gets
created, sends an uevent, userspace copies the fw to the kernel and the
"firmware device" is removed after that, which sends another event.
The event is not used for anything, it's just the logic the driver
core works.
