It doesn't. However, most licences allow derivative works to be created
outside of Intel's control. If one of these derivative work allows the
device to be used in a manner that violates FCC rules and regulations, Intel
remains liable because they a) the provider of the hardware device in
question and b) the provider of the initial software (that spawned the
There is nothing stopping Intel from releasing the firmware, except for the
legal fear that the FCC will hold them accountable for illegal acts
performed with their device.

No. In this case it is not being used "in conjunction with Intel component
products" as it stands alone.

Because fxp is not a wireless device, and thus does not fall under the FCC's
control for RADIO devices. (The normal Class A/B rules for device emissions
still apply, but since the device is a hardwire device, there's nary a way
to change the firmware to be in violation of these rules.)
