Caveat: the last time I used the iwlwifi driver was somewhere between
one and two months ago, during which time there have been several
changes in src related to wifi/linuxkpi stuff.

Hardware: Dell Precision 7550, BIOS revision 1.13.0

Dual stack IPv4+IPv6 worked for me that last time I used iwlwifi.
Here's my relevant configs:

==== begin rc.conf ====
ifconfig_em0_ipv6="inet6 accept_rtadv"
ifconfig_em0="DHCP"

#wlans_iwlwifi0="wlan0"
create_args_wlan0="wlanmode sta"
wlandebug_wlan0="+state +crypto +node +auth +assoc +dot1xsm +wpa"
ifconfig_wlan0="WPA DHCP"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
==== end rc.conf ====

==== begin `pciconf -lv` ====
iwlwifi0@pci0:0:20:3:   class=0x028000 rev=0x00 hdr=0x00 vendor=0x8086 device=0x06f0 subvendor=0x8086 subdevice=0x4070
    vendor     = 'Intel Corporation'
    device     = 'Comet Lake PCH CNVi WiFi'
==== end `pciconf -lv` ====

==== begin dmesg.boot ====

Hopefully this helps. But this is all the info I've got. Please let me
know if you have any questions or comments.
