I'm seeing a lot of posts reference lar_disable like this one for instance. I'm wondering what it does. modinfo iwlwifi just says,

parm:           lar_disable:disable LAR functionality (default: N) (bool)

What is "LAR functionality"?

    If you don't know what it does, then disable it and if it is useful, you will notice it. – Rolf Mar 22 '19 at 14:14

LAR means Location Aware Regulatory

I searched LAR in the source code of Linux wireless driver, only Intel use the LAR term in their code. In their code comment [1, 2, 3] mention the full form of LAR


LAR functionality is a reference to Location-Aided Routing Protocols.

Example papers:

  1. Location-Aided Routing (LAR) in Mobile Ad Hoc Networks
  2. Secure Location-Aided Routing Protocols With Wi-Fi Direct For Vehicular Ad Hoc Networks
