What version of FreeBSD is this? I couldn't reproduce this on head with
a T6 card. Can you please run this in parallel with your ifconfig
commands, note what dtrace logs in response to what command(s), and send
the output to me?
# dtrace -n 'fbt::t4_set_rxmode:entry {trace(arg4)}'

In my experiments the interface did function in promiscuous mode whether
I did "ifconfig cc0 promisc up" or "ifconfig cc0 up promisc".
