Unable to setup a bridge in Alpine Linux

1

I tried these commands:

  incus network create net --type=bridge --target node1.incus
  incus network create net --type=bridge --target node2.incus
  incus network create net --type=bridge --target node3.incus
  incus network create net --type=bridge

Results in:
Error: operation not supported: Unknown device type

But also this is failing:
brctl addbr br0

bridge-utils are installed.

Is it a limitation on Alpine Linux?

my /boot/cmdline.txt:

root=UUID=d6a2d4f8-f86c-4721-9aec-91e5543019ee modules=sd-mod,usb-storage,btrfs quiet rootfstype=btrfs rootflags=subvol=@/sna
ps/@ module_blacklist=ipv6

Blacklisting the ipv6 module caused my problems.
