Description

FreeBSD 11-Current added support for the Intel Dual Band Wireless AC 3160/7260/7265 IEEE 802.11ac network adapters (https://www.freebsd.org/relnotes/CURRENT/hardware/article.html)
via the iwm driver(https://www.freebsd.org/cgi/man.cgi?query=iwm&sektion=4&manpath=freebsd-release-ports).

In the current snapshot(2.4.0.b.20170725.1611) the driver is not loaded and will not create a network interface, but is visible via pciconf:

none4@pci0:3:0:0: class=0x028000 card=0x80708086 chip=0x08b38086 rev=0x83 hdr=0x00
vendor = 'Intel Corporation'
device = 'Wireless 3160'
class = network

There are other people with the same issue when the iwm driver is not supported: https://forum.pfsense.org/index.php?topic=134079.0 and involves copying driver from vanilla freebsd

imho it would have been better to compile them out as modules instead

there is the possibility that the wrong driver will be loaded example: iwm7265fw_fw instead of iwm7265Dfw_fw

it's also possible that this is happening or something similar
https://forum.netgate.com/topic/154497/wireless-interface-iwm0-not-showing-in-gui

iwm8000Cfw: root not mounted yet, no way to load image
iwm0: could not read firmware iwm8000Cfw (error 0)
iwm0: SecBoot CPU1 Status: 0x1, CPU2 Status: 0x3
iwm0: Failed to start INIT ucode: 35

also this is present under 2.5.0

164 iwm3168fw_fw

but not under 2.4.5-p1
