not sure if this is the correct way to get things working, but this diff 
fixes things up on my end (allows the firmware to load):

diff --git a/sys/modules/iwmfw/Makefile b/sys/modules/iwmfw/Makefile
index d38f5424153..73e401b3ea9 100644
--- a/sys/modules/iwmfw/Makefile

+SUBDIR=        iwm3160fw iwm7260fw iwm7265fw iwm8000Cfw iwm8265fw 
iwm7265Dfw

  .include <bsd.subdir.mk>


w/o the diff the iwm8265fw doesn't get built afaict.

cheers,
