As Lars says, we don't yet support anything 11ac, either hardware/driver
wise, or in the 802.11 stack.
I am aware of people working on support for the 7260, though I suspect a
working driver will be some time away. It will also only support a/b/g
and maybe n to begin with - we are quite a way from having 11ac support in
the stack.

Unfortunately, funding is just half the problem - we also need to find a
developer capable of doing the work. The Intel 3160 and 7260 will likely
require a whole new driver - almost no code can be shared between it and
the iwn(4) driver.
Please understand though that getting a driver for the Intel 11ac devices
is seen as a big priority.

Unfortunately, many Lenovo laptops lock the BIOS down in such a way that
they won't boot without the NIC they were shipped with :(

Jack Vogel still supports wired Intel NIC drivers for us, and other Intel
staff support other hardware such as their new storage controllers.

I'm not hugely knowledgeable on the state of drivers, but:
- We have new drivers for the Radeon stuff, in head and 10.1.
- nVidia provide FreeBSD drivers for FreeBSD. I understand that part of
the reason we don't have OpenCL support is because they don't know
there is a demand for it.
- I have no idea what functionality we lack for Nouveau, is that
documented anywhere?
Thanks,
