It does not, and neither does the kernel (it was added in Linux 3.18
and hasn't been backported).

Yes.  He will need to install both the kernel and firmwarepackages from
there:

    apt install -t jessie-backports linux-image-amd64 firmware-iwlwifi

Thank you very much. I will ask my friend to install those two packages from jessie-backports. If he has any feedback, I will let you know.

Best regards.
