Does the speed of light in vacuum define the universal speed limit?

Is light the thing causing the universal speed limit to be $299\,792\,458\,\mathrm{m/s}$? So the universal speed limit would be different if light traveled faster or slower?

Or, is $299\,792\,458\,\mathrm{m/s}$ the universal speed limit anyway and light just goes that fast? Light is just something we commonly associate with it because it goes super fast.

Is Does light in a vacuumdefine the universal speed limit or is 300 mil m/s the limit independently and light just goes that fast?

Is light the thing causing the universal speed limit to be 299,000,000 m/s$299\,792\,458\,\mathrm{m/s}$? So the universal speed limit would be different if light traveled faster or slower.?
