This is because of broadcast filtering.  This feature hasn't been
supported for quite a while and now the firmware rejects the command we
send to it.

The easy fix is to compile iwlwifi without
CONFIG_IWLWIFI_BCAST_FILTERING (which should not be enabled by
default).

I have removed this option from the driver now and will send the patch
to 5.17-rc* as a fix.

Golan, I think we have a bugzilla for this, do you remember?
