Currently the caps are parsed on every firmware reload, causing any channel flags to be cleared. When there is a firmware to interface mode mismatch, the triggered firmware reload causes a reset of the regulatory settings, causing all channels to become available: root@openrouter:/# iw phy phy0 info Wiphy phy0 Band 1: (...) Frequencies: * 2412 MHz [1] (0.0 dBm) * 2417 MHz [2] (0.0 dBm) * 2422 MHz [3] (0.0 dBm) * 2427 MHz [4] (0.0 dBm) * 2432 MHz [5] (0.0 dBm) * 2437 MHz [6] (0.0 dBm) * 2442 MHz [7] (0.0 dBm) * 2447 MHz [8] (0.0 dBm) * 2452 MHz [9] (0.0 dBm) * 2457 MHz [10] (0.0 dBm) * 2462 MHz [11] (0.0 dBm) * 2467 MHz [12] (0.0 dBm) * 2472 MHz [13] (0.0 dBm) * 2484 MHz [14] (0.0 dBm) (...) To prevent this, only parse the caps on the first firmware load during hardware probe, and store them locally to know we have already parsed them.
