Hi Scott,
I am not %100 clear on the status of 11.1-RELEASE support to be honest. 
It looks like in the Makefile that CURRENT is needed (which I'm guessing 
is due to lkpi changes which aren't present in 11.x yet):

<snip>
.if ${OPSYS} == FreeBSD && ${OSVERSION} < 1200039
IGNORE=                not supported on 11.x or older, no kernel support
.endif
</snip>

My understanding is that on CURRENT you should be able to build/install 
the pkg and things should start working.  I haven't had a chance to test 
the port itself yet unfortunately due to some time constraints on my 
end, altho i plan on rebuilding my skylake system later this afternoon.  
I'll report on how that goes and will let you all know.

Cheers,
-pete
