I would be incredibly surprised if this went anywhere, but hey.

The task is fairly simple. Create a patch that adds Radiotap headers by default to the Linux orinoco driver's monitor mode and get it integrated into the mainline kernel driver. The signal and noise levels should be adjusted to provide accurate levels in dBm for ORiNOCO-based devices.

The bounty consists of two parts:
-16.5 BTC for the completion of a patch which will enable Radiotap headers in monitor mode for the orinoco driver.
-33.5 BTC for the integration of above (or later revision) patch for the orinoco driver into the wireless-testing branch (after submitting it to linux-wireless and orinoco-devel for review)

Interested but have no hardware? I will send you a USB ORiNOCO device free of charge if you state your interest in this thread. You will need a USB (B-Type) cable for it, however.

Uninterested because this hardware is ancient and no one uses it anymore? I am unsurprised.
